[Buildroot] [PATCH v3 05/16] qt5: Fix sporadic build failure during top-level parallel build

[Yann E. MORIN]

Hervé, Andreas, All,

On 2021-08-17 10:39 +0200, Herve Codina spake thusly:
> From: Andreas Naumann <anaumann at ultratronik.de>
> 
> When using top level parallel build, independent qt5 packages may be
> built in parallel. Because of their staging dirs being hardlinked, they
> all use the same qt.conf file to manipulate during configure, while
> another qt5 package might already use it. This leads to weird build failures
> because the folders qmake is using are diverted in erratic ways.
> Fix this by actually recreating a non-shared qt.conf file for every package.

Applied to next, thanks! :-)
