Sun nm uses -p to produce the portable output format.

You could use -v:
-v Sorts external symbols by value before they are
printed.
which of course matches the order of the functions in the object file.
This seems to be reasonably portable: GNU nm and the vendor nm's on IRIX
and Tru64 UNIX support it.

I wonder if it might be an option (at least for a DejaGnu-ified libgo
testsuite) to have individual tests per function instead of per
directory? This way, it might be easier to see which subtest is
failing, and (undesirable) interactions between them would be avoided.
