The reason we did the ".foo" --> "_Foo" transformation was
exactly because we didn't want to do crap like this any more.

It's error prone, and is nearly impossible to get working with
every version of the compiler.

Why don't we just put an ifdef __sparc__ thing into modutils
which understands the ".foo" --> "_Foo" translation?
