Turns out OpenBSD was mistakenly including an embedded system fragment,
and thus outputting stabs debug by default.
Once the only needed definition is saved from that file, we happily compile
with default dwarf2. The rest of the toolchain is happy, and any recent
gdb works very well with that...
This obviously improves the stability of the compiler, since dwarf2 output
is so much more well-tested than stabs on elf platforms...

* config.gcc: Don't include embedded systems fragment, switches default
debugging format to ELF.
* config/i386/openbsdelf.h: Add DBX_REGISTER_NUMBER since we no
