When one compiles libraries that include functions that use varargs
with gcc (got that?) the libraries contain unresolved references to
__builtin_saveregs.  This makes the libraries dependent on gcc.  A
better way of handling this is to make the __builtin_saveregs assembly
code in-line (this adds only 4 instructions on a sparc).

This all came to my attention because the X11R5 libraries are now
dependent on gcc.  We are temporarily adding __builtin_saveregs to our
libc so we can run programs without recompiling them (assuming they
are dynamically linked.)
