Don't know about rcc, but the Qt docs are pretty clear that relative 
paths must be used in qrc files:

 
https://qt-project.org/doc/qt-4.8/resources.html#resource-collection-files

I suppose you could just use a symlink to work around this.

PS: For standard icons, a possible alternative solution is to use 
QIcon.fromTheme (only really useful on Linux, though):
