[PATCH v7 08/23] tools build: Append extra host CFLAGS for fixdep

[Leo Yan]

tools/scripts/Makefile.include can add host compiler options through
HOST_EXTRACFLAGS. Make sure the tools build uses those flags when building
fixdep.

Create a local HOST_CFLAGS variable from KBUILD_HOSTCFLAGS and
HOST_EXTRACFLAGS, and pass it to the fixdep build.
