Gabriel and I have been tracking down an include path issue for GCC 6
Advance Toolchain builds (ie, --with-advance-toolchain=...). The solution
that fixes the problem for us is to configure with --with-local-prefix=...
and removing the following hunk from config.gcc. Gabriel has confirmed
this fixes his AT builds (native and cross) and I've verified that this
patch bootstraps with no regressions.
Is this ok for trunk and the GCC 6 branch?

* config.gcc (powerpc*-*-*, rs6000*-*-*): Remove setting of
INCLUDE_EXTRA_SPEC for Advance Toolchain builds.
