Subject: Use the newly minted Makefile.libcompat to implement libsoft
 libraries for the armv6 ABI switch. This also make WITH_LIBSOFT functional on
 the arm platform. As a transition thing, this seems to work even without
 switching the ABI (we basically build the same libraries twice when
 MK_LIBSOFT=yes until the ABI cut over next month). MK_LIBSOFT remains default
 no.
