[issue17781] optimize compilation options

[Matthias Klose]

Matthias Klose added the comment:

most of that can be attributed to the pgo build, which is upstream for a long time. the second thing to do is to build with lto, and see what speedups you get in addition. and it certainly helps to build the interpreter statically (without --enable-shared).

but thanks to confirming my own experience ;)
