According to generated 'configure' the option should not be needed.

  --with-libtool-sysroot=DIR Search for dependent libraries within DIR
                        (or the compiler's sysroot if not specified).

So, if --with-libtool-sysroot is not set it should pick it up from
whatever the compiler is using.
That does not seem to work :(
