Hmm, how do you select right relocations that depend on the ABI selected?
A common macro like "lw $2,foo" may expand in three different ways
depending on which one of "-mabi=<o32|n32|64>" is used and other three
ones for "-KPIC", plus possibly more depending on other options or "foo"
itself. Good luck handling it with "ifdefs".
