Hello,

I believe it's an issue between the kernel-headers version and glibc >= 2.31.
I'm able to reproduce with the Arm ARM 2020.11 and Bootlin toolchain stable
2020.08-1 but not with Bootlin toolchain bleeding-edge 2020.08-1.

The Arm ARM 2020.11 provide 4.20.3 kernel headers while the Bootlin toolchain
bleeding-edge 2020.08-1 provide 5.4.61. Both use glibc 2.31.

Since glibc 2.31, there is a tables with system call numbers that come from
kernel 5.4 [1]. But syscall like __NR_clock_gettime64 has been added since
kernel 5.1 [2]

It seems we need a toolchain with kernel headers >= 5.1 to workaround the
issue.
