how does it have to look like if I want to go without this auxiliary
variable GALLIUMDRIVERS_MESON and instead insert the Python expression
that generates its content directly into ...

... the above assignment of PACKAGECONFIG[gallium]?
I can't get it to work - perhaps it is a problem with escaping things?
