[xmlsec] xmlsec and libtool 2+

[Roumen Petrov]

Hi Aleksey,

After upgrade of xmlsec build system to libtool 2+ I would like to 
propose a small change. The reason is that libtool 2.2.x for windows 
hosts don't create more "wrapper" scripts and create "wrapper" 
executable only.
======================================

======================================
With libtool 2+ and change above we could run tests on linux in emulated 
environment with binfmt-support.




Next is about dynamic loading . The new code require additional changes 
in configure.in for mingw host. Currently I use following:

As I'm not sure that this part of script is final I would like to 
prepare patch later.
The current detection of ltdl always will end with yes in message 
"checking for xmlsec-crypto dynamic loading support .... checking for 
... checking for... yes(!?!?!?)"


With above changes plus change in libxml (see
http://mail.gnome.org/archives/xml/2009-November/msg00012.html )
the xmlsec pass keys and dsig tests in emulated environment with gcc 
4.4.0 for mingw and openssl head version .
The encoding test report failures on decrypt of document but this look 
like end of line problem as the reference files are with CR only.

Thanks for upgrade to libtool 2x
