Hello,

our dunfell based yocto no longer builds in the pkgconfig-native section. I tried it in an Ubuntu 18.04 and Debian 10 Docker container.
The build always aborts as follows:

checking thread related cflags... -D_REENTRANT
| checking for pthread_create/pthread_join... no
| checking for pthread_create/pthread_join in -lpthread... no
| checking for pthread_create/pthread_join in -lpthread32... no

| checking for pthread_create/pthread_join in -lthread... no

I also tried using the commits from dunfell-next in the poky repo as a test. But then the build doesn't even start and I get the following error:

ERROR: ParseError at /work/yocto-optimeas/yocto/meta-openembedded/meta-oe/recipes-extended/libimobiledevice/libplist_2.1.0.bb:9: Could not inherit file classes/python3targetconfig.bbclass | ETA: --:--:--


Does anyone have any idea what is causing this? does anyone have the same behavior?

Many greetings,
Matthias
