As a general comment, I think we should have a single buildbot entry for 
the whole of binutils-gdb.

Given changes to bfd and opcodes can affect gdb, why not build gdb 
alongside the other tools? You don't need to run the gdb testsuite, 
which should make things much more deterministic.

I don't expect the build times including gdb/gdbserver/sim will be much 
longer.
