numo-linalg gem doesn't build with truffleruby+graalvm-22.3.0 on Ubuntu 22.04 or Rocky 9 (RHEL)

[jcasu]

truffleruby+graalvm-22.3.0 is having issues building numo-linalg works fine, btw, on ruby 3.2.0. Please see attached file for the error output. Looks like a BLAS source macro isn't being defined.

many thanks.

It sounds like UNUSED is not properly defined, not immediately clear why.
