Ah. You have hit on the big problem. In the current binutils (ie from
the FSF) there is a working gas and ld FOR STATIC BINARIES ONLY. The
only gas and ld which support dynamic libraries are the old ones
(which don't work for cross compiling). I have been able to build an
entire NetBSD tree with static linking using the FSF binutils, but I
don't think this is of much practical interest to anyone. I have been
planning to do an ELF port of binutils for the ns32k, but can't seem
to find any time.
