-Subject: [PATCH] sh-conf
-
-Likewise, binutils has no idea about any of these new targets either, so we
-fix that up too.. now we're able to actually build a real toolchain for
-sh2a_nofpu- and other more ineptly named toolchains (and yes, there are more
-inept targets than that one, really. Go look, I promise).
