Patch for python311
- Don't build with debug symbols by default, we discard these anyway and it
reduces build time with roughly 1/4th (real) on my Tigerlake laptop with LTO
enabled. If debug symbols are needed use our framework's WITH_DEBUG switch
Tested on 14.0-RELEASE (amd64)
With debug symbols (default)
4m29.16s real 6m38.66s user 17.27s sys
Without debug symbols (-g)
3m13.45s real 5m9.13s user 16.24s sys
- Switch from -flto=thin to lto, there's no parallization so it's actually
slower and produces larger binaries
With -flto=thin (default)
3m13.45s real 5m9.13s user 16.24s sys
-rw-r--r-- 1 root wheel 6332792 Jun 8 07:29 libpython3.11.so.1.0
With -flto
2m42.62s real 4m48.13s user 16.68s sys
-rw-r--r-- 1 root wheel 6224104 Jun 8 07:51 libpython3.11.so.1.0
