To build uClibc correctly we need correct endianness selected in the
crosstool-NG. Xtensa cores may be little- or big-endian, but this
property is static. The toolchain knows the core endianness and doesn't
need options to select it.
Enable ARCH_SUPPORTS_BOTH_ENDIAN and select LE by default. Specify empty
CT_ARCH_ENDIAN_CFLAG so that -m{big,little}-endian don't get added to
the TARGET_CFLAGS, as it's not supported by gcc. Specify empty
CT_ARCH_ENDIAN_LDFLAG so that -EB/-EL don't get added to the
TARGET_LDFLAGS as they are ignored. Select big-endian in the example
xtensa-unknown-linux-uclibc configuration.
This fixes uClibc toolchain build for little-endian cores.

With avr-libc 2.0.0 released, we no longer need to force gcc 4.9.x for
the avr toolchain. So, remove the gcc version constraint and allow it to
follow the default gcc version. There is also no need to force companion
libraries' versions anymore.
The 'experimental' flag was also removed from the description as it
seems to be following upstream development now.

I couldn't get this sample to build. I tried rolling ct-ng back to 1.22
and back to the commit that introduced it, to no avail. Not sure if it
ever built on my machine.
The first problem is the failure to build binutils/gold because of the
missing <pthread.h> in mingw. However, even if CT_BINUTILS_GOLD_THREADS
option is unset, the build dies in configure of the pass-1 of the core CC.
The config.log states that it failed to link with libmpfr.a, which has
a lot of undefined references to symbols like '__imp___iob_func'.
Googling shows that these symbols are some dark Cygwin/MinGW magic and I
do not have the knowledge of these arcana. Let some other MinGWizard fix
it another day.

There is invalid assembly in dmalloc for PowerPC. The issue is that
'stw' expects a memory operand, and =g constraint allows both registers
and memory. Newer GCC tends to choose register even at -O0, resulting in
invalid assembly. Instead, force a register constraint in 'mflr' and let
GCC decide if it wants to store it into memory at all.

This change, as per #222, reduces the number of supported releases of
gcc to the latest branch releases.
I noticed while doing this work that gcc-4.5.4 was never added, so I
moved patches for gcc-4.5.3 to 4.5.4 and updated the
bfin-unknown-linux-uclibc example. Also, 120-siginfo.patch was fixed
upstream in the 4.5.4 release, so this patch is omitted.
I also bumped the avr sample to 4.9.3 from 4.9.2.
With the addition of gcc-5.x, the gcc release team now releases the
major.minor.0 versions, while updates to the branch are available in
svn/git. We'll address that when we get to issue #219. This change just
removes CC_GCC_5_1 and moves CC_GCC_5_2 to CC_GCC_5, and removes
CC_GCC_5_1_or_later and moves CC_GCC_5_2_or_later to CC_GCC_5_or_later.
This is the first of two part changes, as mentioned in #222.
This change is slated for release in 1.22.0. The next change will be
slated for 1.23.0, and will limit gcc versions to what is on
https://gcc.gnu.org under "Release Series and Status", which is
currently 4.9.3 and 5.2.0, although I will also support the previous
supported version. In this example that would be 4.8.5.
Last, but not least, this change also retires AVR32 support.

Some older versions of configure (including the one in GMP 4.3.2)
interpret the $ECHO environment variable as the `echo' utility to
use. CT-NG sets the variable to `:' and exports it if V=0 or V=1
is supplied, breaking the samples using such configure. This currently
includes bfin-unknown-linux-uclibc and powerpc-unknown-linux-uclibc.
Also, correct the description of the V= variable - V=0 is *not* the
default; in fact, default does not correspond to any of the V=[012]

Building cross-gdb in canadian cross requires expat/ncurses for the
host. Currently, 300-gdb.sh only builds expat/ncurses for the target
(for native-gdb). For cross-gdb on regular cross (build==host), expat
and ncurses are expected to be provided by the host.
There are two approaches possible:
- If building for canadian cross, build expat/ncurses for cross-gdb
just as the native-gdb does.
- Promote expat/ncurses to first class citizens and build them as
companion libs during the build of the build-to-host toolchain.
I am leaning towards the latter approach - it would also allow to
specify the versions for expat/ncurses rather than have them hardcoded
in 300-gdb.sh - but would appreciate feedback.

The issue with this sample is that the sh4-* targets in GCC do not
implement __builtin_trap() function. Starting with release 5.1,
GCC inserts abort() calls where NULL pointers are dereferenced. The
elf/dl-conflict.c in glibc is one such place: it calls elf_machine_rela
with NULL `sym' pointer. This causes an undefined `abort' symbol to
appear in the object file and as a result, pulls in some files during
the linking of the dynamic loader that are not supposed to. Eventually,
it results in link error due to multiple definitions of _itoa and some
other symbols.
The right fix would be to implement __builtin_trap() for sh4 in GCC.
A workaround would be adding -fno-delete-null-pointer-checks to
CFLAGS-dl-conflict.c in elf/Makefile. Until either of these happens,
though, pin the GCC version to 4.9.3 - the last that did not generate
`abort' calls. Note that the version where GCC started to generate
`abort' calls is apparently different for different architectures;
the issue in [1] was reported against GCC 4.9.
References:
[1] https://www.sourceware.org/ml/libc-alpha/2014-10/msg00807.html
(similar issue on HP-PA which was resolved by implementing
__builtin_trap)
Options were renamed. However, matching current option names result
in a compile error for strfmon_l.o in glibc: GCC 4.6 detects an
unitialized variable in its own va_arg() implementation. Likely,
an older GLIBC was used when this sample was submitted - which did
not provide -Werror in CFLAGS.
Thus, use most recent GCC (5.2.0) and revert GLIBC_FORCE_UNWIND to
its default value, 'y' (as forced unwind is required with this version).
- Incompatible ISL/CLooG were requested by config after newer releases
of both were brought in.
- Consistency with other samples: save tarballs (which will avoid
downloading them each time from Travis), extra logging.
This should ideally be upstreamed to uclibc maintainers, but with the
last release more than 3 years ago, I wouldn't hold my breath for a
fix being released any time soon.
As of right now, ltrace fails to build. To get CI happy, lets just

The avr-libc manual and most distributions build the AVR 8-bit gcc
toolchain with the "avr" (non-canonical) target.
Some experimentation also led to the conclusion that other (canonical)
targets are not very well supported, so we force the "avr" target for
crosstool-ng as well.
Some patches are required in avr-libc for a toolchain with gcc 5.x to
work. These patches are still not part of any avr-libc release version,
so the config sample currently forces 4.9.x to avoid requiring to clone
avr-libc trunk.

This commit updates the arm-unknown-linux-uclibcgnueabi sample to the
modern age:
- gcc is bumped from 4.4.3 to 4.8.2
- binutils is bumped from 2.19 to 2.24
- gdb is bumped from 7.1 to 7.7
- uclibc is bumped from 0.9.30 to 0.9.33
- kernel headers are bumped to 3.10
- strace is bumped to 4.8
- all companion libraries are also updated
In addition, the ARCH_CPU/ARCH_TUNE configuration options are changed
from xscale to arm926ej-s, with the reasoning that in the ARMv5
ecosystem, ARM926EJ-S cores are much, much more widely used than
Xscale cores.

This patch fixes the download of the avr32 headers in crosstool-ng by
fetching them directly from Atmel's web site instead of the now-broken URL
given by the original author of the avr32-header-fetching modification,
who fetched them from a copy on his own, now-defunct server.
It also adds the necessary logic to extract from a zip file, as that is
how the headers are packaged.
To configure it for avr32 after launching ct-ng menuconfig in an empty
directory:
Paths and misc options ->
Shell to use as CONFIG_SHELL = sh
Target options ->
Target Architecture = avr32
Toolchain options ->
Tuple's alias = avr32
Binary utilities ->
binutils version = 2.18a
C compiler
gcc version = 4.2.2
C-library
newlib version = 1.17.0
Enable IOs on long long = yes
Enable IOs on floats and doubles = yes
Disable the syscalls supplied with newlib = yes
CONFIG_SHELL is necessary to get round the "fragment: command not
found" bug when binutils-2.18 is configured using bash.
