When building gdb for the host, we properly pass the PATH (through
HOST_CONFIGURE_OPTS) during the configure step, but we forget to do so
for the compilation step.
The result of this is that when the Crosstool-NG backend is used, gawk
is built and installed in $(HOST_DIR), as a dependency of the
crosstool-ng package.
Then, the host gdb configure script detects this gawk binary
($(HOST_DIR) is in the PATH), and assumes gawk is
available. Unfortunately, during the compilation step, it fails to
find the expected gawk binary, because $(HOST_DIR) is no longer in the
PATH. This causes the following build failure:
http://autobuild.buildroot.org/results/067d0c2ea01673ba98ec11de2426f1ab92dac800/build-end.log
In order to fix this, we simply call the compilation step of gdb for
the host with $(HOST_MAKE_ENV), as it should have been done from the
beginning.

Xtensa is a configurable processor architecture, which allows to define
additional instructions and registers. The required variant specific
information for the toolchain is delivered in an 'overlay' file, which
needs to be 'untarred' to the corresponding directories after the
source is installed and patched.
This patch provides support for binutils, gcc, and gdb with a very
limited changes to the build scripts. These additions are only executed
for the Xtensa architecture and have no effect on other architectures.

When an external toolchain without thread debug is used, the gdb
package can be selected, but no version can be choosen, since none
match any of the requirements. This leads Buildroot to try to build
gdb for the target without a version being defined, as in the
following build log:
http://autobuild.buildroot.org/results/84e8fd2df0cc22448052a572c2e9a6e03dd137eb/build-end.log
To fix this, we adjust the dependencies of the BR2_PACKAGE_GDB option
so that the package as a whole is not selectable when the required
conditions are not met. Basically, we have the choice of:
* Having a toolchain that supports thread debugging, which is needed
for gdb >= 7.x
* Having BR2_DEPRECATED enabled, which allows gdb 6.8 to be selected,
which doesn't require thread debugging
* Using bfin, since this architectures has a special old gdb version

As stated in commit 555c2585bf, the
Xtensa architecture has been introduced in 2009 and never changed
since its initial introduction. It requires some special handling that
is a bit annoying, and despite our call to the initial developers, and
the announcement of the deprecation of the architecture during the
2012.05, nothing has happened. Therefore, drop support for this
architecture.

When the crosstool-ng backend is used, host-gawk is built as a
dependency of the crosstool-ng package, and therefore an host 'gawk'
binary is installed in $(HOST_DIR).
When the target gdb package is also selected, this unfortunately leads
to a build failure, as reported on
http://buildroot.humanoidz.org/results/f19c0499d08212d8b5100fa9434e1197092957db/build-end.log.
The problem is that the ./configure of gdb detects gawk in the PATH,
but at compile time, it fails to find gawk. This is due to the fact
that the gdb compilation process is started without the correct path.
This patch fixes this by passing $(TARGET_MAKE_ENV) in the environment
of the gdb compilation process.
A better fix would be to switch gdb to the AUTOTARGETS infrastructure
in the future.

Same thing with the SOURCE_CHECK_WGET and SCP functions.

the new API, except for toolchains acquisition. Since there is quite a

When an external toolchain is used, it is very likely that it contains
a pre-built version of a gdbserver that has the same version as the
cross-gdb included in the external toolchain. So, we now provide an
option that allows to copy this pre-built gdbserver to the target.
As the location of the gdbserver in the external toolchain is not
standardized, we only support the CodeSourcery and Crosstool-NG
layouts for the moment. Other locations can be added later.

Similar to how we do for target (ee39d53ce3ee (Fix GDB BFD test linking)).
Gdb comes with an embedded copy of libiberty, but binutils also installs
libiberty.a into HOST_DIR. The gdb configure script tries to link against
this one rather than the gdb version when it checks for ELF support.
This may fail if those versions are not compatible, leading to obscure
error messages from gdb at runtime such as:
I'm sorry, Dave, I can't do that. Symbol format `elf32-$ARCH' unknown.
Fix it by forcing ELF support.

Newer versions of GDB need pthread debugging support if threads are
enabled, which is always the case for glibc but is a configure option
for uClibc.
We have solved this for internal toolchains by selecting the
BR2_PTHREAD_DEBUG option from the GDB selection if needed, but as this
option isn't available when ctng/external toolchains are used, mconf
prints ugly warnings and the build may fail if an external uClibc
toolchain without pthread debugging support is used.
Fix it by introducing 2 more hidden config options:
- BR2_TOOLCHAIN_HAS_THREADS_DEBUG
- BR2_TOOLCHAIN_HAS_THREADS_DEBUG_IF_NEEDED
The first tells us if the toolchain HAS pthreads debugging support,
and is checked by check_uclibc_feature in helper.mk for external uClibc
based toolchains.
The second tells us if the toolchain is ABLE TO provide pthreads debugging
support if threads are enabled, either because it's an internal toolchain
where we can force enable it or an external glibc/eglibc toolchain or
uClibc with the option enabled.
Crosstool-ng forcibly enables this support, so those will always work.
The preconfigured uClibc-based toolchains we have also all enable it.
Finally, show a comment if this isn't the case so the (external toolchain)
user knows why. This is placed outside the choice option, as menuconfig
has a bug where it doesn't show choice selections which only contain
comments.

The gdb tarballs have been re-released after a GPL compliance
issue was found:
http://sourceware.org/ml/gdb/2011-09/msg00030.html
So all versions were re-packaged.
In the process, an 'a' was appended to the version strings, and
unlike the binutils people, the gdb folks are not inclined in
providing legacy symlinks:
http://sourceware.org/ml/gdb/2011-09/msg00036.html
So, this patch fixes the issue by renaming version strings. It is to be
noted that, although the versions got bumped to include an 'a' at the end,
the directory contained in the tarball is still named after the version
string without the 'a'. For example:
- old version : 6.6
- new version : 6.6a
- tarball name : gdb-6.6a.tar.bz2
- directory name : gdb-6.6/
In fact, it does not pose any problem for buildroot, as the extract process
explicitly mkdirs the directory to extract into, *and* strips the first level
of the tree extracted from the tarball.
