Do you mean the patch:
glibc (2.31-10~0) unreleased; urgency=medium

  * debian/patches/hurd-i386/unsubmitted-tiocflush.diff: Cope with
    BSD 4.1-ish ioctl(..., TIOCFLUSH, NULL).

That patch does not improve the go issues. I've re-run the go and libgo
tests from gcc-snapshot-20210108-1. The results are the same. For
example for libgo, see especially the SIGABRT failures:

                === libgo Summary ===

# of expected passes            169
# of unexpected failures        13

Looking at the errors more closely shows:

want nil
