Use the newly minted Makefile.libcompat to implement libsoft libraries

Browse source 
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.
