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.
