Probably just lack of testing. As long as you're not doing FP stuff, you
have very little in way of ABI differences between SH-3 and SH-4
anyways. SH-2 on the other hand I haven't built a toolchain for in
awhile, so that just needs some trivial patching to bring up to date
(actually, I already have some sh2eb patches queued up locally, but
they're not ready due to relying on binutils CVS and other such
