mescc: Mes C Library: x86: Use long for syscalls. 
The Linux signature uses long, also this allows for making
_sys_call and friends architecture-independent.

* lib/linux/x86-mes-mescc/syscall-internal.c (__sys_call_internal,
__sys_call2_internal): Use long.  Update callers.
* lib/linux/x86-mes-mescc/syscall.c (__sys_call, __sys_call1,
__sys_call2, __sys_call3, __sys_call4, _sys_call, _sys_call1,
_sys_call2, _sys_call3, _sys_call4): Likewise.
