After migrating to gcc 4.5.0 my build is reporting these kinds of errors at
link time:
undefined reference to `_savegpr_31'
undefined reference to `_restgpr_31_x'
gcc 4.4.3 didn't emit _savegpr_* _restgpr_* etc. symbols when configured this
way.
powerpc-eabispe-gcc -v
Using built-in specs.

gcc version 4.5.0 (GCC)
Unfortunately I'm not familiar enough with the internals of gcc to take this
any further. Is there any more debugging I can provide?
