Colin Watson 27ef9b07b4 Fix /dev/ptmx rather than excluding makedev
Revert exclusion of makedev from buildd chroots, as it turned out not to
be the problem.  Instead, fix up /dev/ptmx to be a character device node
rather than a symlink to /dev/pts/ptmx, in line with the discussion in
https://bugs.debian.org/817236; I think this is safer than
cherry-picking the fix to debootstrap at this point in a stable release
cycle.

# debootstrap 1.0.76 started creating /dev/ptmx as a symlink to
# /dev/pts/ptmx. Unfortunately, this doesn't work with sbuild, because it
# leaves the ptmxmode mount option at its default of 000, which causes
# builds to be unable to open /dev/pts/ptmx. To avoid this, debootstrap
# 1.0.89 switched to creating it as a device node where possible. See
# https://bugs.debian.org/817236 for details and analysis.
#
# xenial has a version of debootstrap in the range that contains this bug.
# It seems too risky to try to cherry-pick the debootstrap change in
# question in an SRU at this point; instead, just fix things up here for
# buildd images.
