'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.
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
disable it!
When we fix ltrace, just revert this change.

C++ support is enabled in most samples existing in crosstool-ng and is also

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

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.
