From: Matt Fleming <matt.fleming@intel.com>
Currently tools/build has access to all the kernel headers in $(srctree). This is unnecessary and could potentially allow tools/build to erroneously include kernel headers when it should only be including userspace-exported headers.
Unfortunately, mkcpustr still needs access to some of the asm kernel headers, so explicitly special case that hostprog.
