Control: retitle -1 pandas: test fails/crashes on mipsel
arm* = new tests hitting the already-known issue #877754
(which I don't like having open with no user-level warning, but blocking
the transition over it doesn't actually help)
s390x/ppc64 = bug in the tests, not the library
riscv64 = looks NaN-handling-related, possibly in numpy (their
TestBoolCmp.test_float fails as well, but doesn't fail the build due to
#943369), not a release arch
This leaves mipsel as the only RC issue: ~100 failures (many, but not
all, xz compression related), an intermittent crash, and no detailed
output because of a MemoryError while trying to print it(!).
