[1] mentions that memfd_secret is only supported on arm64, riscv, x86 and x86_64 for now. It doesn't support other architectures. I found the build error on arm and decided to send the fix as it was creating noise on KernelCI. Hence I'm adding condition that memfd_secret should only be compiled on supported architectures.
Also check in run_vmtests script if memfd_secret binary is present before executing it.

Good find. Please include the build error in the commit log.
