This is bugfix release of stable libmdbx branch,
on the day of international children's camp «Artek».
It is reasonable to backport this patch to all applicable releases/branches of Buildroot.
The most significant fixes of v0.12.7:
- added workaround for build issues with modern GCC using `-m32 -arch=i686 -Ofast`.
- fixed the cause of the false-positive warning of modern GCC in the C++ API.
- refined DB opening in "recovery" mode and switching to a given meta-page.
