Subject: [PATCH 1/6] qtbase: qmake: always use libname instead of absolute
path in qmake files
In generated qmake files, absolute paths to qt libraries are embedded
and then used in linker flags. However as the libraries can be provided
by qt modules other than the one currently being built, the ebedded
paths can be incorrect.
