Revert syscall split (of commit 55d38162be);
just copy the two syscalls I need for __raise instead.

* lib/linux/arm-mes-gcc/syscall-internal.c (__sys_call_internal): New procedure.
(__sys_call2_internal): New procedure.
(__raise): Use them.
(__sys_call, __sys_call2, __sys_call3, __sys_call4, __sys_call6): Move to...
* lib/linux/arm-mes-gcc/syscall.c: ...here.
* lib/linux/arm-mes-mescc/syscall-internal.c (__sys_call_internal): New procedure.
(__sys_call2_internal): New procedure.
(__raise): Use them.
(__sys_call, __sys_call2, __sys_call3, __sys_call4, __sys_call6): Move to...
* lib/linux/arm-mes-mescc/syscall.c: ...here.
