aborts the build on missing dependencies, with a local override of the
module_selection as 'most', and module_default of the same shared|static
model that was requested through --enable-proxy.

[For trunk, we need to reevaluate the 'most' condition of some of the more
esoteric modules, and simply drop the module_default override; where a user
wants to enable -only- mod_proxy, plus one proxy mechanism, the legacy 2.4.x
behavior retained by this patch is nuts. For one example,
  --enable-modules=few --enable-proxy-yes --enable-proxy_http
is a completely specific and legitimate syntax --- adding 10 other proxy
providers in response to this syntax is absurd.]

script instead tranforming it to Unix Epoch.

This bug was mentioned in the users@ mailing list and outlined in
the following centos bug: https://bugs.centos.org/view.php?id=10940
To reproduce the issue it is sufficient to connect mod-fastcgi
to a PHP script that returns a HTTP response with
the header "Last-Modified: foo". The header will be modified by
script_util.c to "Last-Modified: Thu, 01 Jan 1970 00:00:00 GMT".
Dropping an invalid header in this case seems to be the most
consistent and correct option in my opinion, plus it shouldn't
break existing configurations. Returning Unix Epoch might be
dangerous and should be avoided, but please let me know your opinions.
Moreover this is my first commit outside the documentation court,
I hope to have got the procedure right.
This fix has been tested also with the 2.4.x branch.
