Making the objects match is the prefered option but those changes
require more modifications to the overall make infrastructure then
restructing the comparision and I am not sure that disturbing all the
builds to that extent for the sake of one platform is the best approach.
So far I haven't heard of any platforms other then 32 bit HPPA having
this problem. It might be better to split the difference, modify the
build to use -frandom-seed= for PA in order to fix most of the
comparision issues and then just skip the comparsions on the
lib2funcs.asm file.
