Comment (by jsalort):

 Following up, actually the reason it did not work is because it compiles
 and links with /usr/bin/clang.
 Octave compiles fine with +openblas +gcc11 -sundials.
 However, the graphics don't work for some reason that I haven't figured
 out.
 Also, I have added

 {{{
 if { ${os.arch} eq "arm" } {
     set short_host_name aarch64-apple-${os.platform}${os.major}.x.x
 }
 }}}

 in `post-patch`.
 I don't submit a PR, because there are still issues to be resolved
 (sundials, and the graphics).
