You can compile it so that the gdb binary is aout
(`cd /usr/src/gnu/usr.bin/binutils && make OBJFORMAT=aout), but that's
still a debugger that debugs ELF binaries.
It can't handle aout binaries unless you explicitly configure it to do
so and this ability seems to be broken by the FreeBSD-specific
changes.

Well, on second thinking the idea to build from /usr/src might not
save much.
You need the binutils libraries and friends as aout, so it might be
easier to start from a source that carries everything you need with
it and link it statically.
