QMAKE_LIBDIR_POST still does not live up to its name

If older qt libraries are present in sysroot, qmake links against those instead of the libraries currently compiled. This is related to the problems already fixed with QTBUG-40825.

Steps to reproduce:

1. Install Boot2Qt 5.9.1 jetson-tx toolchain
2. Clone qt/qtbase and checkout dev-branch
3. Configure with following options:

   • ./configure R . -openssl -device linux-jetson-tx1-g++ -device-option CROSS_COMPILE=/home/sanurmen/Qt/5.9.1/Boot2Qt/jetson-tx1/toolchain/sysroots/x86_64-pokysdk-linux/usr/bin/aarch64-poky-linux/aarch64-poky-linux -device-option DISTRO_OPTS='aarch64 boot2qt' -sysroot ~/Qt/5.9.1/Boot2Qt/jetson-tx1/toolchain/sysroots/aarch64-poky-linux/ -extprefix /home/sanurmen/work/install -mysql_config ~/Qt/5.9.1/Boot2Qt/jetson-tx1/toolchain/sysroots/x86_64-pokysdk-linux/usr/bin/aarch64-poky-linux/usr/bin/mysql_config -psql_config /dev/null -tslib -no-xcb -opensource -confirm-license -nomake tests -verbose -prefix /home/sanurmen/work/install -release -nomake examples

1. Start compilation

Expected outcome:

• Compilation of qtbase is successful

Actual outcome:

• Compilation fails with this kind of error message (linked against old library version missing some symbols)
