[issue31354] Fixing a bug related to LTO only build

[Charalampos Stratakis]

I'd say yes. In general python may have been compiled with -flto, but it's still a bit buggy from the compilers' side. It doesn't work well always or at all depending on the toolchain, and even if python was compiled with -flto, that doesn't mean that all c extensions compiled using that python build, would work properly with -flto.

In my opinion that should be a flag reserved for python only, if used for its compilation, and not having it propagated to c extensions, similarly to the PGO related flags.
