The selection of linuxthreads, linuxthreads old or NPTL doesn't make a
lot of sense for external toolchains. So, instead, we :
* Introduce an hidden BR2_TOOLCHAIN_HAS_THREADS option, which must be
selected by toolchain specific options when thread support is
available. Package needing to test thread support should use this
option.
* Move the none/linuxthreads/linuxthreads old/NPTL selection to
Buildroot internal toolchain configuration.
* Add an option in external toolchain to tell if thread support is
available or not in the external toolchain. We assume that glibc
without threads is not possible, as Ulrich Drepper said in
http://sourceware.org/ml/libc-alpha/2005-08/msg00091.html
ffmpeg, dmalloc and openvpn are fixed to use the new
BR2_TOOLCHAIN_HAS_THREADS option. For openvpn, --enable-threads=posix
is no longer used, as the configure script doesn't even understand
this option.

We already handle the stripping of libraries in $(TARGET_DIR) at the
global level, so there's no need to have toolchain-specific option and
code for this.

Instead of letting the user define all the details of his external
toolchain, we define a set of profiles for well-known external
toolchains (CodeSourcery ones only at the moment, can easily be
extended with other toolchains).
Once a profile has been choosen, the user is offered the choice of
either letting Buildroot download and install the external toolchain,
or (as before) to tell Buildroot where the toolchain is installed on
the system.
We of course provide a "custom profile", through which the user can
configure Buildroot to use a custom external toolchain for which no
profile is available.

* ccache is now a normal package (both for the host and the target).
* ccache option is now part of the "Build options" menu. It will
automatically build ccache for the host before building anything,
and will use it to cache builds for both host compilations and
target compilations.
* bump ccache to 3.1.3

Rename the external toolchain directory.
When new backends are here, it will be easier to sort them out
if they are all prefixed the same way.
