    Fix extraneous warning about executable stack.

    PR gold/17578 notes that gold will print a warning about an executable
stack
    when the -z execstack option is given, even when there is no
--warn_execstack
    option. The warning is completely useless and unexpected, since the user
    explicitly requested an executable stack, and did not even ask for
warnings.

    This patch fixes that, and adds an extra warning when --warn_execstack
    and -z noexecstack are both given and an input file requires an executable
    stack.

        * layout.cc (Layout::layout_gnu_stack): Don't warn when -z execstack
        is given.
        (Layout::create_executable_stack_info): Warn when -z noexecstack is
        given but some inputs require executable stack.
