Subject: [PATCH 0/3] Add LoongArch support to nolibc

From: Feiyang Chen <chenfeiyang@...ngson.cn>

Add statx() support to implement sys_stat().
Add support for LoongArch (32 and 64 bit) to nolibc.
It was tested on LoongArch64 only.

The latest QEMU support full-system emulation of a LoongArch64
machine, but for the moment we need to specify the firmware manually.

QEMU_ARGS_loongarch  = -M virt -bios edk2-loongarch64-code.fd ...
