At the moment I wouold say that our testsuite is unreliable enough in
non-validate configurations that this has relatively little value. This
is something we are working on fixing and hopefully things will be more
reliable in the future.
I generally validate the tree prior to cutting a release. This of course
won't catch environment- and distribution-specific issues, but I think
it's a pretty good proxy for correctness.
In other words, unlesss you find yourself looking at the testsuite
output yourself, I think it would be fine to disable it.

As far as I know neither Debian nor NixOS run GHC's testsuite.
