Allow bsd.compat.mk to be reliably included outside Makefile.inc1. Replace explicit TARGET_* variables with COMPAT_* versions defined based on where the file is being included. Also, require that bsd.compat.mk be included directly. It's not going to be widely used so always loading it in bsd.prog.mk doesn't make sense. Instead users can include it directly.

Add the ability to link programs against a compat ABI. Linkage is controlled by two make knobs: WANT_COMPAT - Prefer to link against the compat ABI.
