It's been a long time since I dinked with this stuff, but...

IIRC, there's several levels of strip. One strips everything, save for
standalone binaries (not dependent on run-time linking with a library)
and "safe". Safe leaves the external symbols intact so that the loader
can tell what linkages are needed. I don't remember the parameters, but
the manual should tell you.

I *think* that some symbols are needed for loadable modules for both the
kernel linkage and any references to shared libraries that might be
used. Again, I'm unsure now - to many decaeds have passed since I dinked
with this stuff.
