commit: https://git.buildroot.net/buildroot/commit/?id=a2c9c59d5dcd396361e008f25ded8421d37a382a
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2020.05.x

Qmake configured packages will, by default, use the absolute HostPrefix/Sysroot
pathes set during configuration/building of qt5base for their install
For the per-package host/staging infrastructure, this causes non-qt5base
packages to litter the qt5base folders. In addition, buildroots target-install
step subsequently fails because the respective files are missing from the
per-package sysroot of the package itself.

Fortunately, qmake's built-in pathes can be overridden by placing a custom
qt.conf next to the qmake binary. This is already used to facilitate SDK
relocation. So for per-package path manipulation we can reuse that method, but
need to change the host/sysroot values according to each per-package
