Bad system call error on Android

[Pekka Enberg]

Ren Hiyama reports on Discord:

I downloaded and unzipped the linux arm64 tar gz file and tried to run it, however it shows an error on android:

$ ./turso

... And a lot of error stack 

The "bad system call" means that the Linux kernel it's using doesn't support something. I think it's sys_faccessat2() that's missing. AFAICT, this is a Go bug and will be fixed in 1.21 that's scheduled for August: golang/go@58f6022
