The process hierarchy (from top to bottom) is:
  gmake check

Adding more debugging statements, I see that it hangs in the line
  if (!isatty (slave))

Commenting out this line fixes the issue; all 85 tests in this
directory then pass.

Note: The code in gnulib/lib/openpty.c, which is tested on many platforms,
does not contain an isatty() call in this place.
