PATCH to dejagnu/lib/remote.exp:check_for_board_status

[Jason Merrill <jason@redhat.com>]

[-- Attachment #1: Type: text/plain, Size: 431 bytes --]

The status wrapper adds "<EOL>*** EXIT code n<EOL>" to the output.
check_for_board_status tries to strip this, but the old regexp would only
strip a CR or an LF, not both, so we were left with a trailing CR if the
target uses the DOS EOL convention.  Fixed thus.

OK?

	* lib/remote.exp (check_for_board_status): Remove both CR and LF
	at the beginning of the status wrapper output.
