It will select the default subarchitecture - what may be more
interesting is that it won't complain if the user or binary file has
selected a different subarchitecture.  This is a bit tricky; see
choose_architecture_for_target in arch-utils.c, particularly the
the_default check.

So suppose you have in the future an spu:512K, and gdbserver doesn't
need to know the difference, but it's recorded in the ELF file.  GDB
would object if gdbserver reported "I have an spu:256K".
