Canadian Cross compile for baremetal fails with error;
checking for the value of EOF... configure: error: computing EOF failed
which is due to libstdc++ configure not being able to find stdio.h
Having all modes of the core compiler copyheaders from CT_HEADERS_DIR
(in combination with previous patch for newlib to add a do_libc_start_files
function to copy into the CT_HEADERS_DIR) resolves this.

It's not my day.
linaro_version is a filter. If it is not a linaro toolchain, it will
just be CT_{CC,GDB}_VERSION. If it is a linaro toolchain, CT_{CC,GDB}_VERSION
will be prefixed with 'linaro-' and will not match linaro_version, as
linaro_version will just have the part after 'linaro-'.
This *really* fixes the issue :sigh:

When try to build the static toolchain, binutils failed.
I have checked the libtool script, and found that the following option
-all-static
-static
-static-libtool-libs
are processed in a strange way. If any one of those three options
appears firstly in the cmdline, all others will be neglected. Our
LDFLAGS is ".... -static -all-static -o", so the -static option
takes the real effect, and the -all-static has no useage actually!

Byt the end of the main script, the log file is being moved and
compressed, and the final destination might become read-only at any
time, so we consign stdout/err to oblivion.
This is incorrect, as some actions after may still fail (out of space,
for example).
So, properly restore stdout/err, but also stdin (useless, but harmless)
instead, so the user has a chance to see the error, especially since it
is not logged into the log file.

gcc-4.8 comes with a new library to sanitise memory access:

This library requires some _np parts of the API, which are not

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.

In case we only download or extract the sources, do not fail while
finishing the toolchain: the test-suite directory may not exist, so
we can't chmod it.
Also, use safer constructs that won't trigger the 'set -e' in case of
failure (eg.: "[ ... ] && ..." is not safe in case the test fails).

For some architectures, it is legit to have an alternate value in the
'architecture' part of the tuple. For example:
armv5te-*
armv7a8-*
Besides, some packages expect the tuple to reflect the arch variant
(eg. openMPI) to detect the variant's capabilities (eg. atomic
primitives).
This patch adds an option for the user to specify a suffix to be added
to the arch-part of the tuple.

Toolchains that use the hard-float ABI now are to be denoted by a tuple
ending in *eabihf, while the prevbious *eabi is now an indication that
the toolchain uses the softfloat ABI.
This is purely a cosmetic thing, for distros to differentiate their
hardfloat-ABI ports from their softfloat-ABI ports.
(note: softfloat ABI does not mean that it is using softfloats; it can
be using hardfloat instructions, but using the softfloat ABI).

While most components have their version in the .in file, some
have it in the .in.2 (eg. elf2flt).
Currently, to handle this case, we indiscriminately munge both files,
but this is wrong: in the elf2flt case, if we add a binutils version,
we do not want it to be added to elf2flt, and conversely.
So, for each tool, we need to explicitly know what file to munge.

The current mechanism to check if static linking is possible, and the mesage
displayed on failure, can be puzzling to the unsuspecting user.
Also, the current implementation is not using the existing infrastructure,
and is thus difficult to enhance with new tests.
So, switch to using the standard CT_DoExecLog infra, and use four tests to
check for the host compiler:
- check we can run it
- check it can build a trivial program
- check it can statically link that program
- check if it statically link with libstdc++
That should cover most of the problems. Hopefully.

Currently, extract and patch are skipped as thus:
- using a custom directory of pre-installed headers
- a correctly named directory already exists
Otherwise, extract and patch are done.
The current second condition is wrong, because it allows the following
sequence to happen:
- a non-custom kernel is used
- a previous build only partially extracted the non-custom sources
- that p[revious build broke during extraction (eg. incomplete tarball...)
- a subsequent build will find a properly named directory, and will
thus skip extract and patch, which is wrong
Fix that by following the conditions in this table:
Type | Extract | Patch
----------------------+---------+-------
Pre-installed headers | N | N
custom directory | N | N
custom tarball | Y | N

Now, things have changed (what? when? Dunno...), and some bare-metal
canadian toolchains fail to build if a core pass-1 is not present.
OTOH, a core pass-1, although not needed for non-NPTL builds, does
no harm at all if it is present.
So, unconditionally build a core pass-1 (but still pass conditional
options to the core backend).

During application development it is desirable to enable malloc
debugging and LD_DEBUG support, but the extensive debug spew from
SUPPORT_LD_DEBUG_EARLY is only useful when working on
uClibc's ld.so.

Autoconf can determine that the correct install command includes flags,
e.g., "/usr/bin/install -c". When using this as a command, we can't
enclose the value in double-quotes, as that makes some shells use the
whole expression as a filename:
# this is the value returned by autoconf and stored in CT_install
$ ins="/usr/bin/install -c"
# if we call it with quotes, the command is not found
$ "${ins}"
bash: /usr/bin/install -c: No such file or directory
# removing the quotes lets it work as expected
$ ${ins}
/usr/bin/install: missing file operand
Try `/usr/bin/install --help' for more information.

Currently, we rely on an existing external cross-compiler targetting
the target, to build the C library.
This can pause quite a few problems if that compiler is different from
the one we are building, because it could introduce some ABI issues.
This patch removes this dependency, by building the core compilers
as we do for standard cross, and also by building the binutils and
gcc, for running on the build machine.
This means we no longer need to offer the cross-sompiler selection in
the menuconfig.

Bizarrely enough, the core gcc are not enough to be able to build a
canadian cross, and a real, full cross compiler is required so that
the canadian cross can be properly built... WTF?!? Sigh...
Add a build-frontend, as was done for the binutils and the complibs.
