It's not valid to have "expr@GOTOFF" where "expr" resolves to
something other than "symbol + offset".  Here you've got two
symbols, so "classes" would have to resolve to an absolute
constant.  Furthermore, with the current gas implementation,
"classes" would need to be defined before the reference.

I'll remove the assert from i386_displacement and replace it
with a fatal error message, as it's clearly not some sort of
internal gas error but user input that is causing the problem.
