Applied to master, thanks. I have applied, but to be honest, I believe
we should drop gqview. It has been unmaintained since 2006. There is a
fork called geeqie. Perhaps it makes sense to package it... or not. I'm
not sure this kind of desktop-level applications are really that useful
in the context of Buildroot.
