Actually if I call "mount -t devpts none /dev/pts" inside the chroot
before running the testsuite (even if ran after building zsh in the
chroot), the testsuite passes.

So for some reason the testsuite fails if /dev/pts is just an empty
directory, i.e. /dev/pts/ptmx does not exist in the chroot, but
/dev/pts does.
