x86, boot: Restrict CFLAGS for hostprogs
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. Cc: H.
