Subject: [PATCH 0/4] tools/nolibc: add two new syscall helpers

Hi, Willy

When I worked on adding new syscalls and the related library routines,
I have seen most of the library routines share the same syscall call and
return logic, this patchset adds two macros to simplify and shrink them.

All of them have been tested on arm, aarch64, rv32 and rv64, no new
regressions found.

If this is ok, I will rebase the new syscalls and library routines on
this patchset.

Best regards,
Zhangjin
