Testing issue: arbor

Summary

Summary	Spack package test failure
Package info	arbor-0.9.0
System	JUSUF
Related	none

Steps to reproduce the issue

$ spack spack install --test root arbor

Error message

(Build-)Tests fail because of missing GPUs (JUSUF does not have GPUs on the login-nodes, in contrast to JURECA). To solve this, I added

    # skip running 'make check'
    def check(self):
        pass

as suggested by @elmath, but it would be awesome to have the option to only disable/skip GPU-related tests instead of the whole test-suite.
