Andreas, all,

I attached 2 additional patches, that fix compile issue on x86 platform 
http://lists.busybox.net/pipermail/buildroot/2020-June/285123.html). I 
based my work on top of 2020.05 tag, plus:

- [v6,19/28] core/pkg-infra: Add per-package support in qmake infra 
- [v6,20/28] qt5: Fix pkgconfig search path for per-package 

Description of my patches:

1. The first one is fixing the absolute path added in .pri and .pc files 
when building qt5base. When using sysroot, thos abolute path are 
breaking the compilation because they are pointing to directories 
outside the sysroot.

2. The second one is fixing .cmake files that also contains absolute 
paths after qt5base installation

I'm now able to use full parallel build with per-package with Qt5.

Thank you for your hard work Andreas,

Louis-Paul CORDIER
