That was naive. Can I blame the GCC documentation? ;-) I've dropped
back to the following for testing, as that's what delivered by the
SDK.
MULTILIB_OPTIONS = mcrt=newlib/mcrt=clib2/mcrt=clib2-ts msoft-float
MULTILIB_DIRNAMES = newlib clib2 clib2-ts soft-float
Shared libraries want -fPIC, and since we can't have -fPIC
-msdata=default, we can't have small-data shared libraries. If that's
intentional, then we need a flag to disable building shared libraries
in certain multilib configurations. I don't know how to do that yet.
