I don't see how you could do that since the symbol is associated with an
existing place in memory.  We could put the whole function in a
different segment but that's not the kind of solution I was thinking of.

I was thinking that there might be an unused attribute that could be
pressed into service as a "don't auto export" (doesn't linux/elf have
something like this?) or that there was a way to name the symbol in some
way that wasn't easily available from a C program, like putting a "." in
the name with an asm alias.
