ccache: set COMPILERCHECK to 'none'

This allows ccache to re-use its cache contents even if the compiler
binary mtime has changed. It is the simplest approach to solve this
problem, and it works for the internal, external and crosstool-ng
toolchain backends.

Of course, it leaves the user responsible for invalidating the cache
when necessary, but there doesn't seem to be a real good solution that
allows both to: 1/ keep the cache contents accross builds and re-use
it and 2/ invalidate the cache automatically when the compiler chances
in an incompatible way.

ccache: Force ccache to use its internal zlib

The problem is that without this, ccache would link against the zlib
of the build system, but we might build and install a different
version of zlib in $(O)/host afterwards, which ccache will pick
up. This might break if there is a version mismatch. A solution would
be to add host-zlib has a dependency of ccache, but it would require
tuning the zlib .mk file to use HOSTCC_NOCCACHE as the
compiler. Instead, we take the easy path: tell ccache to use its
internal copy of zlib, so that ccache has zero dependency besides the
C library.

Fixes bug #4808.

package: fix WGET download method

In cf2486bf317e4bbf88c801fb96183ba62be78cc8, we changed from using the
-P option of wget (to set the output *directory*) to using the -O
option (to set the output *file*). Unfortunately, wget -O has a
strange behaviour: it creates an empty 0-byte file even if the
download fails (for example when there is no network connection).

The problem is that then Buildroot thinks the download was successful
and therefore goes on with extracting the tarball.

The following succession of events makes Buildroot think that the
download has been sucessful:

 * Buildroot calls the DOWNLOAD_WGET macro with the URL of the
   official site

   * It tests if the file exists in the download directory, it doesn't
     exist.

   * It calls wget. wget fails to download the file and returns an
     error code, but leaves an empty file with the correct name in the
     downloaded directory.

 * Since the previously download failed, Buildroot tries another
   download from the Buildroot mirror (sources.buildroot.net)

   * It tests if the file exists in the download directory... and it
     exists! So this second download returns with success, and
     Buildroot assumes the file has been downloaded properly.

This scenario brings us with the following result, where the download
fails, but Buildroot continues its execution and tries to extract the
tarball:

$ rm /opt/dl/glib-2.30.2.tar.bz2
rm: cannot remove `/opt/dl/glib-2.30.2.tar.bz2': No such file or directory

Linaro has just released a new pre-built toolchain, available as a
tarball, which is a pure toolchain (only the C library is
included). This makes this new Linaro 2012.01 toolchain usable in
Buildroot, so let's integrate the support for it.

In addition to simply adding the new external toolchain at the usual
locations, this patch allows need to adapt a few things to support
Linaro toolchains. Most toolchains store their libraries in the "lib/"
or "usr/lib" directories relative to the toolchain. Buildroot
toolchains on the other hand, store the libraries in the
"usr/<target-name>/lib" directory. And the Linaro toolchain has
choosen to use the "lib/<target-name>" directory. Therefore, this
patch adjust:

 * The logic to search a particular library when that library needs to
   be copied to the target directory

 * The logic to deduce the sysroot directory from the libc.a file
   location in the toolchain: removing "(usr/?)lib(64?)" is no longer
   sufficient, we need to take into account the "lib/<target-name>/"
   case.

Since the Linaro toolchain generates code for Cortex-A processors
only, the selection of this toolchain is limited to Cortex-A8 and
Cortex-A9.

external-toolchain: adjust check for uClibc static toolchains

The current check for uClibc toolchain was verifying that a
ld-uClibc.so dynamic loader was present. However, with static-only
uClibc toolchains, this does not work. Instead, we check for an
uClibc-specific header file in the sysroot.

external-toolchain: run checks even on extracted toolchains

When the mechanism that allows Buildroot to download external
toolchains automatically was added, all the sanity checks on the
external toolchains were not performed. This commit re-enables those
checks that we already do on external toolchains that are not
downloaded/extracted by Buildroot. This makes the toolchain checks
more consistent accross various configurations.

external-toolchain: details on selecting the multilib variants

Support multilib variants in sub-subdirectories

When an external toolchain has multiple variants organized in
sub-directories, Buildroot only copies the selected sysroot and not
all sysroots. In order to make this work, Buildroot creates a symbolic
link of the name of the original selected sysroot to the main sysroot
to trick the compiler so that it finds its libraries at the expected
location.

I.e, if the toolchain as the following organization (example take on
the ARM CodeSourcery toolchain) :

     .      for ARMv5T
     armv4   for ARMv4T
     thumb2  for ARMv7-A/Thumb

and ARMv4T is selected, then Buildroot will copy the contents of
armv4t/ from the toolchain into its $(STAGING_DIR) and then create a
$(STAGING_DIR)/armv4t symbolic link to $(STAGING_DIR).

However, our logic to do so only works when there was one directory
level for multilib sysroots. But in the MIPS CodeSourcery toolchain
there are multiple levels. For example, the MIPS16 soft-float
little-endian sysroot variant is in mips16/soft-float/el/ compared to
the main sysroot.

This patch improves our logic to support this case. The logic is a bit
more complicated as we don't want to create a symbolic link to an
absolute path, but a symbolic link to a relative path, because we want
the host/ directory to be relocatable.

Improve external toolchain logic to support IA32 Sourcery CodeBench toolchain

The IA32 Sourcery CodeBench toolchain has a relatively special
structure, with the following multilib variants:

 * Intel Pentium 4, 32 bits, the multilib variant is in ./ relative to
   the main sysroot, with the libraries in the lib/ directory.

 * Intel Xeon Nocona, 64 bits, the multilib variant is in ./ relative
   to the main sysroot, with the libraries in the lib64/ directory.

 * Intel Atom 32 bits, the multilib variant is in atom/ relative to
   the main sysroot, with the libraries in the lib/ directory.

 * Intel Core 2 64 bits, the multilib variant is in core2/ relative to
   the main sysroot, with the libraries in lib64/ directory.

So the first two variants are in the same sysroot, only the name of
the directory for the libraries is different.

Therefore, we introduce a new ARCH_LIB_DIR variable, which contains
either 'lib' or 'lib64'. This variable is defined according to the
location of the libc.a file for the selected multilib variant, and is
then used when copying the libraries to the target and to the staging
directory.

In addition to this, we no longer use the -print-multi-directory to
get the ARCH_SUBDIR, since in the case of the 64 bits variants of this
toolchain, it returns just '64' and not a real path. Instead, we
simply compute the difference between the arch-specific sysroot and
the main sysroot.

We also take that opportunity to expand the documentation on the
meaning of the different variables.
