libfabric/1.12.1-GCCcore-10.3.0 fails to build for x86_64/generic

[boegel]

I ran into the following problem when building libfabric-1.12.1-GCCcore-10.3.0.eb (in the 2021.12 pilot) for the x86_64/generic target:

This is a known issue with libfabric, see also easybuilders/easybuild-easyconfigs#13871.

A viable workaround here could be to add --disable-psm3 to configopts when libfabric is build with --optarch=GENERIC on x86_64 in our EasyBuild hooks, or to implement a custom easyblock for libfabric (which would be a more general fix that could be done in EasyBuild).

A workaround for this is implemented in #160 through our EasyBuild hooks
