Hmm; the nested case $host seems odd to me. Maybe a better layout is:
with_linux=no with_osx=no
case $host in
*-*-linux*) with_linux=yes ;;
*-*-darwin*) with_osx=yes ;;
esac
if $with_linux = no; then
if test "x$with_lxc" != xyes
...

That is, use only a single host-detection case statement, and rely on
the results of that for future checks, rather than mixing host-detection
and actions based on host-detection into a nested case statement.
And yes, I trimmed out some of the redundant "" from the shell code in
the example above (the shell word after case does not need "" unless it
contains shell metacharacters to be taken literally, because it is not
subject to field splitting; and $with_linux is exactly 'yes' or 'no' at
the point where it is checked, so it is a safe expansion without quotes;
whereas $with_lxc is user-provided and might begin with - or contain
whitespace).

Mostly looks okay, but probably worth a v2 to make sure the
$host-detection case statement rewrite is still good.
