``[3.3 only] set_fpscr isn't PIC even when __PIC__ defined; bad for
prelinking, causes glibc-3.2.3 check-textrel test to fail''
Correctly address fpscr_values[] in set_fpscr() when compiled PIC.
This is a partial backport of this commit:
2003-08-11 Kaz Kojima <kkojima@gcc.gnu.org>
* config/sh/lib1funcs.asm (__udivdi3): Add .type and .size
information in SHmedia case too.
(__divdi3, __umoddi3, __moddi3, __init_trampoline, __ic_invalidate):
Likewise.
(__set_fpscr): Use an access via GOT for PIC case.
