From 476eda9054df443d094273c8b61fce63d940adfc Mon Sep 17 00:00:00 2001

Subject: [PATCH 21/40] 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.
