encode-mp3 test not working on RISC-V architecture

[geerlingguy]

I'm attempting to run some PTS suites on a RISC-V Lichee Console 4A (see geerlingguy/sbc-reviews#39), using this script — the install runs into:

Phoronix Test Suite v10.8.4

    Installed:     pts/timed-audio-encode-1.0.1

            The installer exited with a non-zero exit status.
            ERROR: cannot guess build type; you must specify one
            LOG: /var/lib/phoronix-test-suite/installed-tests/pts/encode-mp3-1.7.4/install-failed.log

The ERROR: cannot guess build type; you must specify one is likely because this system is on riscv64, but I was wondering where I could add any configuration to specify the build architecture for a test like encode-mp3? I haven't had to customize it in the past even on arm64, but there are far fewer folks out there running on RISC-V so far...

It looks like pts/x264 also fails:

Phoronix Test Suite v10.8.4
