    Thanks for your reminding. I understand.
Maybe it is better to add the following in these cases.

if (tst_kvercmp(3, 17, 0) < 0)
        tst_brkm(TCONF, NULL, "getrandom is not supported");

getrandom() was introduced in version 3.17 of the Linux kernel.

Ubuntu 14.04 gets shipped with kernel 3.13.

Try to upgrade your kernel to a more recent version to get the syscall.
