Bug with Intel compilers -- Meson 1.5.0

[amontoison]

I have the following error when I try to compile the package GALAHAD with Intel compilers:

ERROR: Unhandled python exception

    This is a Meson bug and should be reported!

system parameters

• Plain native build
• windows-latest and ubuntu-latest of GitHub Actions.
• Python 3.12.0
• Meson 1.5.0

[thesamesam]

Did older versions work? I have a feeling they did.

[dcbaker]

I suspect this got broken in the option refactoring work that's been going on

[amontoison]

Yes, it worked with previous versions of Meson.
We observed this bug with CI because we install it using pip install meson and it downloads the most recent version.

Can you try the PR I just posted?
