From: Weijie Gao <hackpas...@gmail.com>
The <bits/syscall.h> from musl loongarch64 arch contains some
indirect syscall definitions:
#define __NR3264_fcntl 25
#define __NR_fcntl __NR3264_fcntl
This will result in incorrect contents generated by make_syscall_h_sh:
[__NR3264_fcntl] = "fcntl",
To fix this issue, all macros staring with __NR3264_ should be also
copied to the generated syscall-names.h
