Description: Include the multiarch include directory in klcc's path
 The multiarch include directory, /usr/include/<triplet>, needs to be
 explicitly added to klcc's path; without this, klcc is incompatible
 with recent Ubuntu versions of linux-libc-dev and fails to find any asm/
 headers.
 .
 This change is safe to apply on non-multiarch-enabled systems, since
 $(DEB_HOST_MULTIARCH) will evaluate empty.  However, upstreaming should
 probably wait until we have a way to get this path information in a
 vendor-neutral manner.
