Well, we could also change the symbols file to similarly redirect things
to the appropriate set of packages.  I think it supports the same
functionality.  But yes.  Sorry, I hadn't thought through that.

This is the problem: I think this does matter.  If the MESA libGL ever
includes any symbols that aren't in the NVIDIA library, which doesn't seem
that horribly unlikely, linking would then fail because libGL.so would
point to the wrong library.  Since we have a solution to keeping the *.so
file up-to-date, I think we should leave it just in case.
