This patch fixes .so links in man pages.
It's needed because of the configure option -

    --program-suffix=${_php_version}

The changes made by this patch should be the same as the changes made by this
block of code -

    _regexp='^[[:space:]]*\.so[[:space:]]'
    for file in $(grep -l -e "$_regexp" -R .); do
    	vsed -i "$file" -e "/$_regexp/"'s=^[[:space:]]*\.[^.]*=&'${_php_version}=
    done

Where _php_version is defined in the template file.
