Comment # 2 on bug 1213615 from Arin Lares

Apologies, I had been meaning to actually set up a test build myself to try
this, but haven't had the time to sort it out. I believe if you just removed
the "-DQUARKS=ON" flag it should work.

I cross-referenced Debian and Arch's packages, since they're two I can point to
with the files in the "right" spot, and they seem to omit -DQUARKS=ON in their
builds, and I don't think I've ever used it building from source.

SuperCollider pulls quarks from Github, yes, but they usually go in the
~/.local/share/SuperCollider/Extensions/ExtensionName directory.

Looking at the .spec file I also believe further changes will need to be made
to refer to the proper directory, since this should change the location the
plugins install to.
