Bleah, turns out we were using ld -x on the object files before
building them into a library.  Of course this made local symbols
disappear from .symtab.

Anyway, it seems that my fellow OpenBSD developers are happy with
compiling all system libraries with -g, which of course is much better
;-).

I'll send a message to the GCC mailing list about -g1 & DWARF2.
