it is an egcs bug. egcs-1.1.1-1c failss to build working bsd_comp.o,
ppp_deflate.o, and hfs.o; egcs-1.0-2e.ppc.rpm builds it perfectly. i'm
getting a newer build of egcs right now, to see if it's fixed.

the unhandled relocation was from egcs-1.1.1-1c using the standard
flags (no -fpic). i didn't expect it work w/ -fpic, but i thought it
might work better and it appears to, since it stopped insmod from
complaining about relocations and instead complain about the symbol
offset table (though it may just complain about the offset table
before finding the relocation problem, thus -fpic might not actually
make a difference).
