[PATCH, ARM, v2] PR target/68059 libgcc should not use __write for printing fatal error

libgcc/config/arm/linux-atomic-64bit.c uses __write to print an error
message if the 64bit cmpxchg method is not available in the kernel.

__write is not part of the public libc abi, so use write instead.
(user code may define write in iso c conforming mode and then the
error message may not be visible before the crash.)

The return type in the declaration of write is fixed too.

OK for trunk and backporting?
