util/abuild: Have abuild generate the .xcompile if it doesn't exist

Previously if .xcompile was missing, abuild would silently ignore the
error. With https://review.coreboot.org/c/coreboot/+/34241 we now check
the return code so abuild started failing.

We should generate the .xcompile if it doesn't exist. The Makefile will
handle that so we include it as the first Makefile.

We then need to override the default target so we don't use the one from
the Makefile.

BUG=b:112267918
TEST=ran abuild and made sure it generated a .xcompile in the root.
