[U-Boot] ppc -Os and _restgpr_##_x errors

[Mike Frysinger]

am i the only one seeing errors like:
board/esd/cpciiser4/libcpciiser4.o: In function `board_early_init_f':
board/esd/cpciiser4/cpciiser4.c:139: undefined reference to `_restgpr_26_x'

i'm using a gcc-4.5.x toolchain here.  should we import crtsavres.S from Linux 
to fix this ?
