spec: cleanup
    
    Several cleanup changes:
    * The acinclude.m4 does not seem to be needed anymore.  I actually
    don't know why it was originally added (very long time ago) but
    now even 'autoreconf' works fine — so lets see what will happen.
    * Don't autoreconf as it is not needed.
    * Trim lines.
