Looks like this broke lib32 builds via it ending up using
the default:

-target armv7-unknown-freebsd

instead of the correct:

-target armv7-unknown-freebsd15.0-gnueabihf

I've suggested in the past that the default for FreeBSD's
-m32 for aarch64 should be made to be (stated for 15 now):

-target armv7-unknown-freebsd15.0-gnueabihf

but that has not happened and the build environment must
deal with provding the proper target explicitly.
