Subject: [PATCH v1 03/11] tools/nolibc: include crt.h before arch.h

The crt.h provides a new _start_c() function, which is required by the
new assembly _start entry of arch-<ARCH>.h (included by arch.h), let's
include crt.h before arch.h.

This '#include "crt.h"' doesn't let the new _start_c() work immediately,
but it is a base of the coming patches to move most of the assembly
_start operations to the _start_c() function for every supported
architecture.
