    Issue 50580 - Perl can't be disabled in configure
    
    Bug description:
    Due to incorrect use of AC_ARG_ENABLE macro arguments' semantics some
    calls like ./configure --disable-* and --enable-*=no worked
    unexpectedly like --enable-*=yes.
    
    Fix description:
    As this issue affects several ./configure options all were fixed. The
    fix uses the fourth argument of the AC_ARG_ENABLE to set the default in
    case no option was provided. In case an explicit --disable-* or
    --enable-* argument was provided to ./configure the respective $enable_*
    variable is implicitly populated by autoconf, hence subsequent
    if-else statements take care of additional operations based on the
    variable's value.
    
    For the record, some implementations of the options pre-set the default
    value before the AC_ARG_ENABLE in case the respective $enable_* variable
    has not been set. This is a correct approach, hence left as is.
