freebsd-nq/usr.sbin/uathload/Makefile
Warner Losh f0e44ca337 Document why we use -z nonexecstack in the Makefile since it
is so unusual. Turn off mis-match warnings for building uathload
because the firmware .o file is produced in a way that we
can't get to match exactly. This fixes the build on mips,
so stop excluding it from the build.

# non-executable stack, so ld doesn't properly mark his executable as

# platforms that support his feature (otherwise signals don't work).
# Note: Newer versions of ld than is in the tree ignore -z.
