Fix for Ubuntu 20.04 complaining about "dlclose@@GLIBC_2.2.5"

[gitterdude]

Ubuntu 20.04 is still supported for a few more months so if anyone still using that wants to compile guitarix-0.46, here's a patch you'll need :

Save the above to dl-fix.patch in the "guitarix" source folder and run patch -p0 < ../dl-fix.patch after ./waf configure in "trunk"

There's probably a proper way of handling this but it's a simple, quick fix that works.
