Upon reflection, I believe that this would be the solution to the
issue.  Besides fixing this problem, it would permit FSF gcc to
consistently link files compiled by Darwin gcc, which seems like a
good thing to me.

Unfortunately, since I don't have a Darwin system, I can't easily
write a patch.  However, it's easy to do for anybody who has the
source code for the Darwin compiler.  Just add a file like
rs6000/darwin-tramp.asm and put in the definitions of saveFP and
restFP.  Then add the name of the file to LIB2FUNCS_EXTRA in
rs6000/t-darwin.  It sounds like saveFP and restFP will normally be
used together, so it should be fine to put both functions in the same
file.
