Subject: [PATCH] gnu: libfabric: Depend on PSM2 only on supported systems.

From: Ludovic Courtès <[email-masked]>

Fixes a regression introduced in
2a6ea3895bf554a70c699a1013d75ffa5407bcad, that would make ‘libfabric’
unsupported on non-x86_64 systems.

* gnu/packages/linux.scm (libfabric)[inputs]: Define ‘if-supported’.
Use it for ‘psm’ and ‘psm2, and remove labels.
[arguments]: Remove ‘--enable-psm2’, which is unnecessary.
