Yes. I replaced the optional GMP package, i.e., upgraded it to 6.1.1.

Yes. But someone should make the doctests more robust w.r.t. this.

A patch for my Haswells has positive review, but isn't merged yet.
(tol changed from 1e-14 to 1.1e-14; see also #21121, a follow-up.)

Good question. Passed when rerun separately. Digging in ptestlong.log
I found:
sage -t --long --warn-long 68.2 src/sage/homology/simplicial_complex.py
**********************************************************************
File "src/sage/homology/simplicial_complex.py", line 2813, in
sage.homology.simplicial_complex.SimplicialComplex.is_cohen_macaulay
Failed example:
X.is_cohen_macaulay(ZZ)
Expected:
False
Got:
[Errno 2] No such file or directory:
'/home/leif/.sage/temp/tunguska/16183/dir_5o8pnH/16223.out'
False
**********************************************************************
So apparently not related to GMP, just another flaky test. (Although I
don't recall having seen that before.)
