Subject: checksyscalls: ignore fstat to silence build warning on LoongArch
Date: Tue, 7 Mar 2023 15:59:00 +0800
fstat is replaced by statx on the new architecture, so an exception is
added to the checksyscalls script to silence the following build warning
on LoongArch:
CALL scripts/checksyscalls.sh
<stdin>:569:2: warning: #warning syscall fstat not implemented [-Wcpp]
