Compiling the kernel in ELF implies having an ELF GCC and binutils

It does NOT mean that you have an ELF GDB, or that the ELF GDB
you do have works properly.

I'd make the core dump format a.out until we're positive that the
ELF core files are correct and readable by the ELF GDB; a new
version of which HJ just uploaded to tsx-11.
