When building libxcb, the variable XCBPROTO_XCBPYTHONDIR must point to
the location where the Python modules needed to run the c_client.py
program are installed. The path
$(STAGING_DIR)/usr/lib/python2.6/site-packages was hardcoded. However,
it doesn't work when the version of Python installed on the host is
Python 2.5.
Therefore, add a little bit of magic to compute the host Python
version.
We also verify that Python is available on the host, as we don't build
it in Buildroot.
Fixes bug #1531.

Since new configuration options have been added in 0.9.31, the value
of these configuration options should be determined, either by the
default configuration file we provide, or by uclibc.mk process.
The locale generation process should probably be improved in order to
allow building other locales than just en_US.

UCLIBC_HAS_NFTW is a new knob in 0.9.31, which allows the obsolete and
deprecated ftw() to be compiled-out separatly from nftw(), which is
part of POSIX. nftw() should probably be enabled by default in uClibc,
and a bug has been opened about this on uClibc bug tracker
(https://bugs.busybox.net/show_bug.cgi?id=1597).
nftw() is, for example, used in Gtk+.

When compiling GDB for target (in my case i386) it links
wrong BFD library from host OS. This prevents GDB from compiling
support for ELF and thus GDB is unusable on target.

Multilib toolchains provide different versions of the base libraries
for different architecture variants. For example, the ARM Codesourcery
toolchain provides base libraries for ARMv5 (default), ARMv4t and
Thumb2.
Depending on the -march= argument passed to gcc, the sysroot used by
the compiler is therefore different. This means that the sysroot
location in CROSS-gcc -v cannot be used. Instead, we must use
CROSS-gcc -print-sysroot when available and fall back to the old way
if unavailable.
Moreover, we cannot simply copy the full sysroot as we used to do,
because the sysroot organization of multilib toolchain is more
complicated. In Codesourcery toolchains, we have :
/
etc -- for ARMv5
lib -- for ARMv5
sbin -- for ARMv5
usr -- for ARMv5 (includes headers)
armv4t
etc -- for ARMv4t
lib -- for ARMv4t
sbin -- for ARMv4t
usr -- for ARMv4t (no headers!)
thumb2
etc -- for Thumb2
lib -- for Thumb2
sbin -- for Thumb2
usr -- for Thumb2 (no headers!)
So we have the default ARMv5 architecture variant that is installed in
the main directory, and we have subdirectories for the ARMv4t and
Thumb2 architecture variants.
Copying the full sysroot to the staging directory doesn't work. All
our packages are based on the fact that they should install libraries
in staging/usr/lib. But if ARMv4t is used, the compiler would only
look in staging/armv4t/usr/lib for libraries (even when overriding the
sysroot with the --sysroot option, the multilib compiler suffixes the
sysroot directory with the architecture variant if it matches a
recognized one).
Therefore, we have to copy only the sysroot that we are interested
in. This is rendered a little bit complicated by the fact that the
armv4t and thumb2 sysroot do not contain the headers since they are
shared with the armv5 sysroot.
So, this patch :
* Modifies how we compute SYSROOT_DIR in order to use -print-sysroot
if it exists. SYSROOT_DIR contains the location of the main sysroot
directory, i.e the sysroot for the default architecture variant.
* Defines ARCH_SUBDIR as the subdirectory in the main sysroot for the
currently selected architecture variant (in our case, it can be
".", "armv4t" or "thumb2"). ARCH_SYSROOT_DIR is defined as the full
path to the sysroot of the currently selected architecture variant.
* Modifies copy_toolchain_lib_root (which copies a library to the
target/ directory) so that libraries are taken from
ARCH_SYSROOT_DIR instead of SYSROOT_DIR. This ensures that
libraries for the correct architecture variant are properly copied
to the target.
* Modifies copy_toolchain_sysroot (which copies the sysroot to the
staging/ directory), so that it copies the contents of
ARCH_SYSROOT_DIR, and if needed, adds the headers from the main
sysroot directory and a symbolic link (armv4t -> . or thumb2 -> .)
to make the compiler believe that its sysroot is really in armv4t/
or thumb2/.
Tested with Codesourcery 2009q1 ARM toolchain, Crosstool-NG ARM glibc
and ARM uClibc toolchains.

The copy_toolchain_lib_root function was making the assumption that
all libraries were stored inside the /lib directory of the sysroot
directory. However, this isn't true for certain toolchains,
particularly for the libstdc++ library.
The function is therefore reworked to find the library and its related
symlink either in /lib or /usr/lib in the sysroot, and copies it at
the same location in the target directory.

Since BR2_RECENT was enabled by default, we do not want entries marked
BR2_RECENT (and thus appearing by default in Buildroot) to disappear.
Therefore, all the entries marked BR2_RECENT are converted as
non-deprecated. We can later decide, on a per-entry basis, to add
BR2_DEPRECATED to some of them. But at least, this commit doesn't
change the default current behaviour of Buildroot.

This variable, together with the FIXME comment, has been added has
part of Eric Andersen's « Major buildroot facelift, step one » commit
that occured in October 2004.
Since then, no real usage has been made of OPTIMIZE_FOR_CPU, and the
initial intention has probably been lost in the memories of the
implementors.
Therefore, get rid of the variable, and just use $(ARCH) at the two
locations the variable was used.

The toolchains built with buildroot use specially crafted paths for their
sysroot and prefix. Fix that by asking gcc where it finds a file we
know by relative path to the sysroot.
This has the side effect of greatly simplifying the sysroot detection
in every cases tested so far (BR toolchains, CT-NG toolchains, and
CodeSourcery toolchains).
Fixes bug #851.

When gmp/mpfr is needed for the host (E.G. when using an internal toolchain),
the host-lib{gmp,mpfr}-source targets weren't added to HOST_SOURCE, so

there we should probably use HOST_<package>_DEPENDENCIES for -source
