Here is the bare-metal/dependency bit.  In this patch, _ARM_BARE_METAL
is only defined if neither RDP or RDI support is available, but my
expectation is that "something else" (configure, libgloss, etc.) will
provide an option to define _ARM_BARE_METAL even when RDI support is
available, so that (as in my original patch) you can have RDI support
for semihosted system calls without relying on it from crt0.

Thanks,
