oh wow. nice find... with that diff, some c++ files are still built at
the start of configure, and some leengthy 'Generating the * bindings/pyi
file' steps are still done during configure, but that's still a large
win...

time make configure -> 6mn
time make MAKE_JOBS=24 -> 5m46.40s real 61m22.39s user 39m33.70s system

will test qgis at runtime shortly.
