Bug 279585: lang/python311: Improve build times
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D279585



--- Description ---
- 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=3Dthin to lto, there's no parallization so it's actually
slower and produces larger binaries

With -flto=3Dthin (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
