[PATCH] correct installation of mod_dontdothat

Hello,

The installation of mod_dontdothat was moved to make install-tools,
however the trunk code tries to install with libtool which fails with
the message: cannot install mod_dontdothat.la to a directory not ending
in [...]/lib/apache2/modules

The attached patch fixes this. This was mentioned earlier here:
http://mail-archives.apache.org/mod_mbox/subversion-dev/201302.mbox/%3C87ip5yhlrd.fsf@ntlworld.com%3E

This can be seen working with an rpm package of the nightly trunk
tarballs here:
https://build.opensuse.org/package/show?package=subversion&project=home%3AAndreasStieger%3Asvn18

[[[
* build.conf
  (mod_dontdothat): install as apache module
]]]

Regards,
Andreas
