Blackfin lib1funcs patch

This fixes a problem with the upcoming FD-PIC patches for the Blackfin: 
since calls in a shared library go through PLT entries, they may clobber 
call-clobbered registers even if we know that the called function 
doesn't modify them.  So we need to avoid using them to save certain 
values across a call.
