The modern compilers and code seem to require extra steps to avoid DEBUG errors,
Move debug tuning configuration from recipes to an include file to address these
errors.

Introduce separate variables to avoid the :remove operations, such DEBUG_OPTLEVEL,
BUILD_OPTLEVEL and OECMAKE_WEBKIT_NO_INLINE_HINTS

Just a note about this patches: I had perf reproducibility issues [1][2]
after taking this series and I believe this is linked with this patch. I
suspect this is not directly related with it, but more with the issue we
have had with perf reproducibility last week.

So I dropped this patch for now, but I will take it a bit later this
week and try to go further. I still wanted to provide some feedback
here. Also, if anyone believes this issue IS related with this series,
please share your thoughts.

Hi

I clone the branch of you on contrib

  https://git.openembedded.org/openembedded-core-contrib/log/?h=mathieu/master-next-success

  https://git.openembedded.org/bitbake-contrib/log/?h=mathieu/master-next-success

And do oe-selftest without the debug build patches, the issue we have had with perf reproducibility still exist

$ oe-selftest -r reproducible.ReproducibleTests.test_reproducible_builds
