Pull up following revision(s) (requested by uwe in ticket #596):
	lib/libc/arch/powerpc/genassym.cf: revision 1.5
	lib/libc/arch/powerpc/gen/swapcontext.S: revision 1.8
PIC code clobbers %r30 so we need to update the saved oucp with
caller's %r30 manually.  Makes old context happy when it needs to do
more function calls after restore.
