That was a fast reply from phone, and I seemed to write it wrongly. In
this case Qt uses PIC, which is the right thing to do for libraries
(and Qt needs it that way).
PIE implies PIE so (and here is what I miss wrote above) PIE should
not be added if PIC was used.

Moreover PIC is more suitable for libraries, so it should be the right
choice here.

Hope that helps, and sorry for my typo in the first mail.
