The x86/x86-64 CodeSourcery toolchains use some weird locations for
the gdbserver binary:
$ find . -name 'gdbserver'
./i686-pc-linux-gnu/libc/atom/usr/bin/gdbserver
./i686-pc-linux-gnu/libc/atom/usr/lib/bin/gdbserver
./i686-pc-linux-gnu/libc/core2/usr/bin/gdbserver
./i686-pc-linux-gnu/libc/core2/usr/lib64/bin/gdbserver
./i686-pc-linux-gnu/libc/usr/lib/bin/gdbserver
./i686-pc-linux-gnu/libc/usr/lib64/bin/gdbserver
Notice that it's sometimes hidden in a usr/{lib,lib64}/bin
directory. This patch changes the gdbserver logic to also try in this
location.

This commit converts gdb to the package infrastructure, and therefore
moves it from toolchain/gdb to package/gdb.
The target package is now visible in "Package selection for the
target" => "Debugging, profiling and benchmark". The main option,
"gdb", forcefully selects the "gdbserver" sub-option by
default. Another sub-option, "full debugger" allows to install the
complete gdb on the target. When this option is enabled, then
"gdbserver" is no longer forcefully selected. This ensures that at
least gdbserver or the full debugger gets built/installed, so that the
package is not a no-op.
The host debugger is still enabled through a configuration option in
"Toolchain". It is now visible regardless of the toolchain type (it
used to be hidden for External Toolchains). The configuration options
relative to the host debugger are now in package/gdb/Config.in.host,
similar to how we have package/binutils/Config.in.host.
Since gdb is now a proper package, it is no longer allowed to 'select
BR2_PTHREADS_DEBUG' to ensure thread debugging is available when
needed. Instead, it now 'depends on
BR2_TOOLCHAIN_HAS_THREADS_DEBUG'. This option, in turn, is selected by
the different toolchain backends when appropriate. The
'BR2_TOOLCHAIN_HAS_THREADS_DEBUG_IF_NEEDED' option is removed, since
we no longer need to know when it is allowed to 'select
BR2_PTHREADS_DEBUG'. Also, the 'BR2_PTHREADS_DEBUG' option is moved to
appear right below the thread implementation selection (in the case of
the Buildroot toolchain backend).

Previously, the crosstool-NG backend did depend on the top-level
Buildroot's .config to detect changes in the toolchain options,
using a tentatively-clever heuristic, which also included the full
Buildroot's version string to push down to set the components' versions
strings.
In doing so, any commit in the Buildroot tree would imply a complete
rebuild of the toolchain, even in the case the toolchain options did
not change, thus being a large annoyance (to say the least).
As Buildroot never guaranteed that toolchain options would be detected,
even less handled, and that the internal backend does neither detect nor
act on toolchain options changes, and delegate that to the user, there
is no point in individualising the crosstool-NG backend's behaviour.
This reasoning also applies to the depdency on the crosstool-NG's bundled
.config file, too.
So, just drop the not-so-clever heuristic, and just build the toolchain
once, leaving to the user the responsibility to explictly ask Buildroot
to rebuild the toolchain.

The existing Microblaze toolchains that we have have the annoying
property of being based on a very old glibc version: 2.3.6. Xilinx
provides newer toolchains with glibc 2.14, generated by Crosstool-NG,
but they are only available as part of a huge Git repository that
contains the gcc, Linux, binutils, glibc sources unpacked (4.4 GB
total), which makes is very unpractical.
I contacted the Xilinx person who did those toolchains, but they
apparently didn't intend to change that anytime soon.
So, we have created a tarball for those toolchains, adding a
README.txt file in the tarball that points back to the original
location that contains the source code for them. Those tarballs are
hosted on sources.buildroot.net.
This commit then adds support for those two new external toolchains,
one for little endian Microblaze, another one for big endian
Microblaze.

The external toolchain wrapper sets sysroot etc. to an absolute path.
By changing this to a relative path, it is possible to move the host
directory to a different location and still have a working build
system.
This only works for a downloaded external toolchain. For a pre-installed
external toolchain, it is possible to move the host directory to a
different location, but not the external toolchain directory (it does work
if the external toolchain directory lies within the host directory). For
an internal or crosstool-ng toolchain, there is no wrapper so updating the
sysroot path should be done in a different way.

This commit fixes the exact same problem than
21a0c11a90, but for the gdbserver
build. The problem is that when you use the Crosstool-NG toolchain
backend, gawk gets built as a dependency of Crosstool-NG. So the gdb
configure scripts detects it, and assumes it is in the PATH (because
the gdb configure step gets run with TARGET_MAKE_ENV).
But then, the build fails, because it tries to run gawk, but gawk
isn't in the PATH, because we forget to use this TARGET_MAKE_ENV
variable when building gdbserver.

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:

As discussed during the ELCE 2012 Buildroot Developers Meeting, we no
longer want to support the possibility of building a toolchain for the

known to be broken or cause problems for a long time without anyone
providing fixes for it.
In addition to this, Buildroot is inherently a cross-compilation tool,
so the usage of a native toolchain on the target is not really
useful. Many newcomers are tempted to use this possibility even though
it is clearly not the intended usage of Buildroot.

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

ld-linux*.so may not be present in lib/ directory, it could be
in lib32 and/or lib64 only. But check_glibc reports
"Incorrect selection of the C library" in this case, which is
not true.
Fixed by extending the search to SYSROOT/*/*.

Since 11017f081f, the Crosstool-ng
backend generates toolchains that have a prefix inconsistent with what
Buildroot expects. Buildroot expects a "buildroot" vendor name, while
Crosstool-NG builds toolchain with the "unknown" vendor name.
This is causing build failure such as:
http://autobuild.buildroot.org/results/15b2c0e50a81b86dd13af684c9254df2bc0df8de/build-end.log
Fix this by changing the vendor part of the tuple used by Crosstool-NG
to "buildroot".

Yann E. MORIN says:
"Although eglibc can be configured to include/exclude parts of the
features, it seems to not be in wide use, if at all."

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.

BR2_SPARC_TYPE is a hidden configuration option that is only used for
the configuration of uClibc, therefore, we move it from
target/Config.arch.in to toolchain/uClibc/Config.in.

BR2_ARM_TYPE is a hidden configuration option that is only used for
the configuration of uClibc, therefore, we move it from
target/Config.arch.in to toolchain/uClibc/Config.in.
We also add a comment that explains that this stuff is only useful for
uClibc <= 0.9.32. Starting from 0.9.33, uClibc build process simply
uses the compiler flags to find the ARM processor that should be
used. So, someday, we'll be able to remove this.
