PS1:

I also think libosmocore should be more resilient and the behaviour we want here is "make sure _GNU_ […]

This is like attempts to force LTO or randomly add -ffast-math, the expected behavior if random flags and defines are added by "the environment" is that everything breaks, just like distro provided stack protectors and other stuff that interfered with simtrace fw builds and had to be disabled.

The assumption is that we know what is defined and enabled at the top of a translation unit.
