[uClibc] Install toolchain from buildroot

No, there aren't any automated way to do it. Buildroot developers
recommend to use "toolchain" instead of "buildroot" to create
toolchains. However, I personaly think that it would be nice to be able
to install the toolchain produced by buildroot.

You have two solutions :

 1) Use the toolchain produced by buildroot directly where it was built
: build_ARCH/staging_dir. (Simply add
$BUILDROOT_PATH/build_ARCH/staging_dir/bin in your PATH).

 2) Tweak the Makefile so that the toolchain will be generated in an
other directory. I succeed in doing this with the old version of
buildroot (when there was no configuration tool). It simply involved
modification of the STAGING_DIR in the main Makefile. This allows to
generate the toolchain in an other directory, eventually accessible to
other users. I don't know if it's still possible to do it with recent
versions of Buildroot.
