[etc]

So, at a wild guess, it looks like the symbol “_PyRuntime” is defined
in one module (pylifecycle.o) which is compiled non-PIC, and is being
referenced in another module (thread.o) which was compiled as PIC. Or
maybe it’s the other way round.

How you managed to end up with inconsistent flags for different parts
of your build, I don’t know. But that’s what needs to be fixed.
