PyQt: Adjusting the BUILD. We do not want to be specific about things like --enable=QtCore.

If you do then all the PyQt modules have to be specified as --enabled=$WHATEVER.
So we let it find what it wants on its own. The --qsci-api is OK to use and does not
force a pendanticy about manually enabling the rest of the modules.
