Hello all,

I updated the layers of my project to the current dunfell branch tips. See here: https://gitlab.com/manuel_wagesreither/bora-proj/-/commit/de631634d7556987d2551d0cedca8f67530bc78d

Since then, the build is failing with the following message:
```
ERROR: ParseError at /home/manuel/bora-proj/meta-openembedded/meta-oe/conf/layer.conf:104: unparsed line: 'DEFAULT_TEST_SUITES:pn-meta-oe-ptest-image = " ${PTESTTESTSUITE}"'
```

Indeed this line, and even more the one after look strange.
https://github.com/openembedded/meta-openembedded/blob/master/meta-oe/conf/layer.conf#L104
```
DEFAULT_TEST_SUITES:pn-meta-oe-ptest-image = " ${PTESTTESTSUITE}"

NON_MULTILIB_RECIPES:append = " crash"
```

When I replace the : with _, things seem to work. I can't make sense of that. Did the syntax change? If so, why doesn't bitbake understand the new syntax? I thought bitbake is included in one of the layers.

Thanks, Regards,
Manuel
