[Buildroot] [PATCHv2 0/7] Introduce BR2_ENABLE_RUNTIME_DEBUG

[Thomas De Schampheleire <patrickdepinguin@gmail.com>]

From: Thomas De Schampheleire <thomas.de_schampheleire@nokia.com>

Hello,

This patch series started with as main goal to fix the performance degradation
found when testing gRPC in combination with BR2_ENABLE_DEBUG.

Its implementation strives to settle a discussion that has happened several
times, regarding the CMAKE_BUILD_TYPE that Buildroot should set, by not forcing
anything upon the user but allowing the choice.
See commit message in patch 3/7 for references to this prior discussion.

Additionally, it cleans up some related changes done in specific packages.

After this series, there are still packages that set CMAKE_BUILD_TYPE
explicitly, but the associated comments indicate that they are needed to avoid
build failures, so they are not touched.

v2: fix sysrepo after comment by Jan Kundr?t (thanks!)


Best regards,
Thomas
