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

hg init a
cd a
hg init b
echo x > b/x

echo '# should print nothing'
hg add b
hg st

echo '# should fail'
hg st b/x
hg add b/x

echo '# should fail'
hg add b b/x
hg st

echo '# should arguably print nothing'
hg st b

echo a > a
hg ci -Ama a

echo '# should fail'
hg mv a b
hg st
