Skip specific libs on build

[qtacc32]

Hello,

is it possible to skip the following libs on build? They don't seem to be used by any tools:

Qt5CLucene
Qt5Concurrent
Qt5Sql
Qt5Test

And these are used by a few tools, but I don't need the assistant or any print support (However I think it's not easy to remove the dependencies):

Qt5Help
Qt5PrintSupport

Thanks!
