build testsuite or not?

[Jens Petersen]

Okay I have one more question about my packaging of ghc for Fedora.

For long I always build the testsuite for every release perf build on all archs
(for an example see the build.log links on
https://koji.fedoraproject.org/koji/buildinfo?buildID=1086491).

Is this a useful meaningful thing to do?

I thought it good to have it as a reference for ghc builds on Fedora
and EPEL, but it does add a considerable amount of time to builds
(specially for the slower ARM arch's)  so it is not without cost.

So I am wondering how useful it is to continue running the testsuite
for each "production" build I do.
What do others and other distros, etc do for final releases?

Thanks, Jens
