autoreconf 2.68 runs libtoolize AFTER aclocal

[Matthias Andree]

Greetings,

I've recently added LT_INIT([disable-static]) to openvpn, and figured
that autoreconf will run aclocal -I m4 first, and only then libtoolize.
 I find this is the wrong order, because libtoolize may populate m4/, so
that I have to run autoreconf twice.

I propose that autoreconf runs libtoolize earlier so that it can then
launch aclocal on an up-to-date m4/ directory.

(Note that libtoolize encourages users to use a separate m4 directory.)

Best regards
Matthias
