MacOS Tahoe openBLAS installation issue with v2.1

[grantfirl]

Description

Starting from a fresh spack-stack configuration using the unified environment, I'm running into an issue during installation of openBLAS. I'm following the instructions for macOS from https://github.com/JCSDA/spack-stack/wiki/New-Site-Configs. I'm on an M4 mac using apple-clang@21.0.0 and gcc@12.5.0. It appears as though I'm running into the issue described in the note for clang>15. That is, I'm getting an error with:

dyld[27888]: duplicate LC_RPATH

This is despite adding

flags:
ldflags: '-Wl,-ld_classic'

to sites/packages.yaml

To Reproduce

Described above, but on M4 mac, follow the instructions for new-site-configs with clang@21 and gcc@12.5.0

Expected behavior

openBLAS installs correctly and the spack install can complete

System, compiler, code, ...

Mac M4, clang@21.0.0, gcc@12.5.0, spack-stack@v2.1

@grantfirl I am not entirely sure, but we are just about to merge #2003 that fixes openblas and many other issues. All credits for this work go to @mathomp4. Maybe it's worth waiting for that PR being merged and then trying again.

@grantfirl Yes, I think this was one of the things I hit getting things working on my macOS update. One of the updates was moving to the latest OpenBLAS as I think older versions in spack had some macOS issues.
