[PATCH]: Loosen up annota1.exp test.

[msnyder@cygnus.com]

This test often fails because different targets behave slightly differently.
I'm making the regular expression more flexible, so that it does not care
how many times the target calls flush_cached_frames() or breakpoints_invalid().

2000-06-02  Michael Snyder  <msnyder@seadog.cygnus.com>

        * gdb.base/annota1.exp (run until main breakpoint): Loosen up
        the regular expression: accept an (almost) arbitrary sequence of
        "frames-invalid" and "breakpoints-invalid" messages both before
        and after the "starting" message.
