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

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 ? -mike
