From: Kees Cook <keescook@xxxxxxxxxxxx>
commit a5a319ec2c2236bb96d147c16196d2f1f3799301 upstream.
When HEADER_ARCH was introduced, the MRPROPER_FILES (then MRPROPER_DIRS)
list wasn't adjusted, leaving SUBARCH as part of the path argument.
This resulted in the "mrproper" target not cleaning up arch/x86/... when
SUBARCH was specified. Since HOST_DIR is arch/$(HEADER_ARCH), use it
instead to get the correct path.
