* arm/crt0.S: Copied from newlib and it now also sets up stacks for
        FIQ and IRQ mode, plus calls hardware_init_hook() and
        software_init_hook() if present.
        * arm/libcfunc.c, arm/swi.h, arm/syscalls.c: Copied
        from newlib.
        * arm/Makefile.in: Build crt0.o, rdpmon-crt0.o, rdimon-crt0.o,
        librdpmon.a, librdimon.a - support file for "bare" setup, as well
        as "RDP" and "RDI" monitors.
        * arm/coff-rdpmon.specs, arm/elf-rdpmon.specs,
        arm/coff-rdimon.specs, arm/elf-rdimon.specs: gcc specs files to go
        with above mentioned support libs and startfiles.

/* Support files for GNU libc. Files in the C namespace go here.
Files in the system namespace (ie those that start with an underscore)
go in syscalls.c.
Note: These functions are in a seperate file so that OS providers can
overrride the system call stubs (defined in syscalls.c) without having
to provide libc funcitons as well. */
