Subject: [PATCH 19/36] Ensure target gcc headers can be included

There are a few headers installed as part of the OpenEmbedded
gcc-runtime target (omp.h, ssp/*.h). Being installed from a recipe
built for the target architecture, these are within the target
sysroot and not cross/nativesdk; thus they weren't able to be
found by gcc with the existing search paths. Add support for
picking up these headers under the sysroot supplied on the gcc
command line in order to resolve this.

Upstream-Status: Pending
