[contrib] Fix match pattern for summary lines in validate_failures.py

[Diego Novillo, 2012-03-02 20:41:44]

This fixes an edge case in parsing summary lines.  Some times, the
description field is missing (e.g., 'FAIL: libstdc++/abi_check'), so
the space that the pattern was looking for does not exist.

I've changed it to match any whitespace, which includes '\n'.  I also
made it print the line that it fails to parse, in case there are other
problems like this in the future.

David, this should fix the failure you were getting in your merge.
Let me know if it doesn't.

	match pattern for the summary line.  If there is a parsing failure,
	show the line we failed to parse.
