[BUG] POWER: undefined reference to `_restgpr_25_x'

Dear Heinrich,

I'm not sure if it's a good idea (and supposed to work) to use a 64
bit compiler for a 32 bit application.  It might be missing some of
the needed gcc libraries.

This patch is linewrapped, right?

I can't see how adding -Wno-error=address-of-packed-member would be
related to fixing undefined reference to `_restgpr_31_x' errors.

This is apparently unrelated, too ?
