perl-5.41.13 fails t/op/readline_nb.t on unthreaded builds

[sisyphus]

Description
There is no problem with threaded builds of 5.41.13, but both mingw-w64 and msvc unthreaded builds fail t/op/readline_nb.t as follows:

D:\comp-1510-ucrt\perl-5.41.13\t>..\perl -I..\lib op/readline_nb.t
ioctl implemented only on sockets at op/readline_nb.t line 22.

Lines 22 and 23 are:

$in->blocking(0)
  or skip_all("Cannot make pipe non-blocking");

Steps to Reproduce
Build and test perl built in accordance with the below configuration.
(The given perl -V is for the mingw-w64 build. I can also provide perl -V output for one of my msvc builds, if need be.)
