[Bug-wget] wget: configure.ac: gnutl > openssl ordering patch and libtool support

[Alex Damb]

 Hello,

This patch for configure.ac replaces logic of searching ssl backend: if not 
specified with --with-ssl=openssl, --with-ssl=gnutls or --with-ssl=no, then, 
first, tries to find gnutls library and, if failes, then tries to find openssl. 
In addition, it adds LT_INIT call to call libtool for specifying rpath option.  

Motivation: not defining --with-ssl=openssl and LDFLAGS="-I/opt/openssl/path 
-Wl,rpath,/opt/openssl/path" in case, when openssl or gnutls is correctly 
installed in non-standard locations, but with providing correct pkg-config files

steps:
tar xf wget-1.18.tar.xz
cd wget-1.18
patch < ../wget-1.18-configure.ac.patch
libtoolize
autoreconf
./configure ...

wget-1.18-configure.ac.patch
