I am pretty sure that this will not work correctly with the existing Clang EasyBlock. Reasons include for example the removal of GCC_INSTALL_PREFIX, see easybuilders/easybuild-easyblocks#3373 (comment). Because of this, Clang 19 won't work as well.

easybuilders/easybuild-easyblocks#3373 implements a way more robust EasyBlock, being used in some other EasyConfig PRs, e.g.: #22517, but this requires EasyBuild 5.0.

We don't even get that far:
