On Ubuntu 18.04, I managed to make build and doc ok with cython
capabilities:
$ sage
┌────────────────────────────────────────────────────────────────────┐
│ SageMath version 9.8.beta6, Release Date: 2022-12-21 │
│ Using Python 3.10.8. Type "help()" for help. │
└────────────────────────────────────────────────────────────────────┘
┏━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━┓

sage:
sage: %%cython
....: def f(int n):
....: cdef int i=1
....: return n+i
....:
sage: f(4)

But then running tests fails from the start with a (ModuleNotFoundError: No
module named 'Cython')
$ sage -tp -all
too many failed tests, not using stored timings

Unhandled SIGABRT: An abort() occurred.
This probably occurred because a *compiled* module has a bug
in it and is not properly wrapped with sig_on(), sig_off().
Python will now terminate.
