Here's an update (everything looks good now). After umount-ing
everything in the chroot, I did this as root (on the host):

address@hidden:/srv/chroot# rm -rf xlmi/
address@hidden:/srv/chroot# mkdir -p /srv/chroot/xlmi
address@hidden:/srv/chroot# debootstrap --arch=amd64 
--unpack-tarball=/var/cache/jessie_bootstrap.tar jessie /srv/chroot/xlmi 
>xlmi-debootstrap-log 2>&1
address@hidden:/srv/chroot# <xlmi-debootstrap-log sed -e'/^I:/d'
[no output--good]
address@hidden:/srv/chroot# cat >/etc/schroot/chroot.d/xlmi.conf <<\EOF

> description=debian-8 cross build
> directory=/srv/chroot/xlmi
> users=greg
> groups=greg
> root-groups=root
> # type=plain
> EOF
address@hidden:/srv/chroot# exit

and then, entering the new chroot as root:

schroot --chroot=xlmi --user=root --directory=/
address@hidden:/# dpkg --add-architecture i386
address@hidden:/# cat >/usr/sbin/policy-rc.d <<EOF
> #!/bin/sh
> exit 101
> EOF
address@hidden:/# chmod a+x /usr/sbin/policy-rc.d
address@hidden:/# dpkg-divert --divert /usr/bin/ischroot.debianutils --rename 
/usr/bin/ischroot
Adding 'local diversion of /usr/bin/ischroot to /usr/bin/ischroot.debianutils'
address@hidden:/# ln -s /bin/true /usr/bin/ischroot
address@hidden:/# mount -t devpts devpts /dev/pts
address@hidden:/# mount -t proc proc /proc
address@hidden:/# apt-get update
[...snip unremarkable output...]
address@hidden:/# apt-get --assume-yes install g++-mingw-w64-i686 automake 
libtool make \
>  pkg-config git zsh bzip2 unzip sudo wine >apt-get-log 2>&1

and now, examining that log as a normal user:

/srv/chroot/xlmi[0]$<apt-get-log sed -e'0,/^Preconfiguring/d' 
-e'/^Preparing\|^Unpacking\|^Configuring\|^Selecting\|^Setting 
up\|^Processing\|^Adding\|^update-alternatives\|^(Reading database/d'

(three cheers for policy-rc.d)

I see nothing weird with 'mount' or 'ps'.
