[Buildroot] [git commit] toolchain-external: add missing symlink for Linaro toolchains

[Thomas Petazzoni]

commit: http://git.buildroot.net/buildroot/commit/?id=b3e3d5fc28b26291d48adad96e92e27c86183673
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

In 11ec38b6950 ("toolchain-external: fix Linaro ARM toolchain
support"), we fixed the support for Linaro EABIhf toolchains by adding
a /lib/arm-linux-gnueabihf -> /lib symbolic link. This is needed
because the dynamic loader looks for libraries in
/lib/arm-linux-gnueabihf rather than the usual /lib, but Buildroot
installs all libraries in /lib.

However, we forgot that the dynamic loader also loads libraries from
/usr/lib/arm-linux-gnueabihf rather than /usr/lib, so this patch fixes
that by adding the necessary symbolic link.
