octave-gsl: Add missing patchfile

[ryandesign]

Description

Fixes "fatal error: 'ov-scalar.h' file not found" which occurred due to failure to locate Octave's include directory.

Closes: https://trac.macports.org/ticket/69246

Instead of adding the nearly 4000-line configure patch, I added the much smaller configure.ac.in patch and then made the port run bootstrap to regenerate configure.ac and configure.

This built for me on macOS 12 x86_64, but it also worked for me before this change, so we need to see if it works in CI and Marius you may want to test it on your system as well.

Fixes "fatal error: 'ov-scalar.h' file not found" which occurred due to failure to locate Octave's include directory.

Closes: https://trac.macports.org/ticket/69246

Based on the CI build failure on macOS 14 arm64 this unfortunately hasn't fixed it:

checking for Octave's canonical_host_type... fatal: caught signal Trace/BPT trap: 5 -- stopping myself...

checking for Octave's include directory... fatal: caught signal Trace/BPT trap: 5 -- stopping myself...

checking for ov-scalar.h... no
configure: error: ov-scalar.h header not found

On my Mac I noticed that when it was checking for these two things, the Terminal window deactivated, as if it's trying to run some GUI thing to make these determinations. That seems doomed to fail. It shouldn't need to start a GUI to find its include directory and host type.

@Schamschula do you want to merge this or go for another solution? If you don't want/need this PR please close.

Unfortunately, the issue where it starts a GUI session happens while attempting to install several other octave packages as well.

The gsl package issue has not been fixed upstream.

[ryandesign]

Closing. This doesn't fix the issue. Nobody develops this software anymore so it will never be fixed.

[Schamschula]

Agreed!

I probably should remove the Portfile.
