[U-Boot] [PATCH v9 11/18] sandbox: Add support for calling abort()

[Simon Glass <sjg@chromium.org>]

This function is useful to signal that the application needs to exit
immediate. It can be caught with a debugger (e.g. gdb). Add a stub for it
so that it can be called from within sandbox when an internal error
occurs.
