According to John Polstra:

Here is John's fix, adapted to egcs. The fix was made on pgcc 980122 but it
should apply mostly cleanly on every version of either egcs or pgcc. I was
able to build a shared lib with our bsd.lib.mk after that. egcs doesn't
have a STARTFILE_SPEC so I added our own (I'm not sure about it).
I'll send them to the egcs folks.
