gdb: Workaround stringop-overread warning in debuginfod-support.c on s390x

Browse Source 
For some reason g++ 11.2.1 on s390x produces a spurious warning for
stringop-overread in debuginfod_is_enabled for url_view. Add a new
DIAGNOSTIC_IGNORE_STRINGOP_OVERREAD macro to suppress this warning.

include/ChangeLog:

	* diagnostics.h (DIAGNOSTIC_IGNORE_STRINGOP_OVERREAD): New
	macro.

gdb/ChangeLog:

	* debuginfod-support.c (debuginfod_is_enabled): Use
	DIAGNOSTIC_IGNORE_STRINGOP_OVERREAD on s390x.
