I'm remembering more about this now --- COFF line numbers aren't
*meaningful* in the absence of linker symbols.  They indicate source
files by symtab indices.  Or some such.  So I think it's always got to
be harmless to ignore line number info when you don't have symbols.

(I'm so out of it.  I could be completely wrong about what this patch
even does.  If what I'm saying is nonsense, just say so and I'll go
figure out what I was really thinking.)
