manpage build: fail early when xmlto is not available

When we try to build manpages with xmlto and sed, but xmlto is
missing fail at the xmlto stage.  Otherwise, one may run `cd doc;
make' and miss the warnings like:

  xmlto: not found
  sed: hg.1: No such file or directory

and end up with empty files installed as manpages.

#!/bin/sh

rm -rf a
hg init a
cd a

echo foo > foo
hg ci -qAm0
chmod +x foo
hg ci -m1
hg co -q 0
echo dirty > foo
sleep 1
hg up -q
cat foo
hg st -A

echo '% validate update of standalone execute bit change'
hg up -C 0
chmod -x foo
hg ci -m removeexec
hg up -C 0
hg up
hg st
