[issue38980] Compile libpython with -fno-semantic-interposition

[Ammar Askar]

Just for a quick datapoint: llvm/clang do this by default and you need an explicit `-fsemantic-interposition` to disable it http://lists.llvm.org/pipermail/llvm-dev/2016-November/107625.html

It seems to me that the performance gains here really outweigh any weird usage of LD_PRELOAD.
