Recent GCC (4.4+) performs out-of-line epilogues in some cases, when optimizing for size. It causes a link error for _restgpr_30_x (and similar) if libgcc is not linked.
It actually increases size with very small binaries, due to the fixed size of the out-of-line code, and not having any functions that actually need to restore more than 2 or 3 registers. But I don't see a way to turn it off, other than asking GCC to optimize for speed -- which may also increase size for some boards.
