[x86] Exclusion of incorrect include headers paths for MCU target
Exclusion of /usr/include and /usr/local/include headers paths for MCU target.
Differential Revision: http://reviews.llvm.org/D14954
Could you elaborate a bit on what this change actually does? The log says that it's supposed to exclude include paths, but the changes don't seem to be doing anything related to include path manipulation at all. Nor do they seem to have anything to do with x86.
