You didn't say which operating system you have on your "DIGI UL6 SBC".

Therefore I'd recommend to try the newest m4 tarball, from
  
https://gitlab.com/gnu-m4/ci-distcheck/-/jobs/artifacts/master/raw/m4-snapshot.tar?job=check-optimized
instead of m4-1.4.17. This tarball supports more operating systems than
the one of m4-1.4.17 (because it uses the newest gnulib).
