fixed ld.so to properly save all regs when binding PIC functions. We no

longer need the special case (PIC) code to push args when calling cerror.

inline call to sigreturn original idea from jason downs <downsj@CSOS.ORST.EDU>
...
we want this to be done for everything including non-PIC code as longjmp()
does non-standard things with regs and wouldn't like it if the user replaced
the sigreturn() stub.
