I see.  My personal feeling is to not care about this.  We tell all our
users (and our IDE) to assemble files using the GCC driver; this keeps
all configuration in one place and everything works like a charm.

Interesting, you use fdpic for full Linux too?  We have only been
looking at it for uClinux so far, but of course SH has a working PIC
model already and I don't know if FRV/bfin do besides FDPIC.
