tweak LLVM easyblock to only run dynamic linker check if `clang` is being built #3952

Crivella · 2025-10-07T14:31:15Z

The EB attempts to run the clang sanity check on sysroot builds even if clang is not being build (form -minimal builds).
Thanks @bedroge for reporting this.

Fixes

Compilation test for the dynamic-linker is ran only in case clang is being built
Minor fix to allow properly working with --sanity-check-only and --module-only

@Crivella there's a typo in the easyconfig names here (LVM).

I'll give this a try in EESSI/software-layer-scripts#103.

Thanks hope the bot gets only the last one, also running a rebuild of minimal on my machine

FAIL (build issue) LLVM-18.1.8-GCCcore-13.3.0-minimal.eb (partial log available at https://gist.github.com/Crivella/c471495e21d27ddbefcf6dc9872620b7)

Notes

All tests failed in failed_to_discover_tests_from_gtest
I will redo an upload with a --sysroot=/ --module-only once i finish rebuilding without sysroot (not sure it is worth fixing those failing tests in this PR)
