python310 @3.10.4_0+lto+universal: Undefined symbols

[ryandesign (Ryan Carsten Schmidt)]

Saw this problem when installing python310 @3.10.4_0+lto+universal on the mountainlion buildbot worker. python39 @3.9.12_0+universal built fine.

It doesn't seem like things should need to be universal on the buildbot workers. I certainly haven't requested that. But a great many things are getting installed universal on the lion and mountainlion buildbot workers only. It may be happening because libomp defaults to universal and libomp is a dependency of many clang compilers and many clang compilers do get installed as a necessity for building other ports. Presumably I could disable libomp's universal variant to avoid this.

I wonder if the toolchain can't handle universal and LTO at the same time. Any difference if you build with -lto?
