'make oldconfig' results in asking the user about options not explicitly
set in the defconfig. Instead of copying, run 'conf --defconfig', as in
the normal sample's build sequence. Also, invoke 'conf --oldconfig'
directly, with a -s option, to avoid spamming with useless
"configuration written to .config" messages.

With current name, 'make saveconfig' is broken for this sample. Also, it
is confusing to have a sample named 'nios2-elf-mingw32' while show-tuple
refers to it as 'nios2-spico-elf' and saveconfig attempts to save it
into 'i686-w64-mingw32,nios2-spico-elf'.

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.

(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
disable it!
When we fix ltrace, just revert this change.
This is also in reference to bug #115

.. and set CT_TARGET_VENDOR to w64. Otherwise config.gcc doesn't
pickup the right files for include_next (and probably many other
things go wrong too).
w64 has been the correct vendor for absolutely ages now on all
distributions that provide MinGW-w64 cross compilers.

C++ support is enabled in most samples existing in crosstool-ng and is also
supported by AVR.
As pointed out in pull request #124 in the crosstool-ng github, Arduino based
projects willing to use this toolchain will require C++ support.

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.

As posted on http://www.eglibc.org/
====================
EGLIBC is no longer developed and such goals are now being addressed
directly in GLIBC.
====================
I'm not interested in maintaining build support for unsupported
software.
Older branches of crosstool-ng continue to have eglibc support.
If you find issues with older branches, I'm always open to pull
requests.
Removing eglibc also frees up glibc cleanup and build optimization.

Use a more coherent naming for the options. This will help commonalise
the native case (e.g. NPTL on Linux, win32 on Windows), and add alternate

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.
The resulting toolchain was tested by building a Busybox-only system
with Buildroot, and testing it under an ARMv5 Qemu emulation.

In make-3.8x, the $(wildacrd) function would sort the entries,
while in make-4.x, it would just return the entries in any
unpredictable order [*]
Use the $(sort) function to get reproducible behaviour.

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.
Prepared against crosstool-ng mercurial trunk on 31 March 2012.
