[Buildroot] [git commit] Makefile: also unexport PKG_CONFIG_LIBDIR

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=bdf472d5bf9b90322c38886814e29bdf8921c5af
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Similar to how we do it for _PATH / _SYSROOT_DIR. Buildroot gets fairly
confused if the user has set up a custom PKG_CONFIG_LIBDIR, so ensure
it gets unset.
