FWIW: I've fixed some bigger layers where pkgconfig was causing quite a few
build failures,

e.g. meta-webosose needed it in around 30 recipes (included in
https://github.com/shr-project/meta-webosose/commits/dunfell)
meta-ros layers I'm still working on, sofar over 50 recipes (
https://github.com/ros/meta-ros/pull/939)

One interesting case I wanted to mention here was collada-dom in meta-ros:
https://github.com/ros/meta-ros/pull/939/commits/4e790a7de5e740eae3084a925a8a23f575ddf410

including this layer.conf change caused collada-dom not to fail with
reasonable error about missing pkgconfig-native, but triggered textrel QA
issue and it was actually caused by pkgconfig not being available where
do_configure "silently" failed to find system bzip2 and minizip due to
missing pkgconfig and built own version instead which lead to this textrel
QA issue.

There might be many more recipes like this, which build something
differently without pkgconfig available, without triggering any QA check
like in this case. It might be useful to compare at least buildhistory
results with and without the layer.conf change to see what else was changed
unexpectedly.

Cheers,
