You must be using an ancient version of that compiler, since AFAIK it
understands -m64 now. Could you use a more recent version?

You missed some of the required information in your email:

mpn/add_n.asm is a symlink for what file?

Could you show some of those lines?
(you many need to remove the last line of mpn/m4-ccas so the file doesn't 
disappear)

How about dropping the xtarget/xarch options, or using -xarch=native64 
maybe?
