[Darwin, PPC] Move the out of line register save/restore to an endfile.

Part 1 of fixes to build and link conditions for older Darwin versions.

We have been including these endfiles in libgcc, which means that we have to
append -lgcc even when using shared libgcc.  In preparation for revision of
libgcc split this into an endfile.
