This is fine with me.

Though I too would like to hear from Joel about the rtems bit.

I've seen rtems configure patches fly by before, and IIRC, they tend
to just just make rtems an alias for bare-metal elf.  That seems to
be supported by other gdb/configure.tgt !x86 rtems stanzas.

I'm curious since that file contains support for old BSD a.out
ports (that is, !elf), and I'm proposing removing a.out support
in another patch.

Joel, does rtems really need anything in i386bsd-tdep.c?

Thanks,
