Re: [Crash-utility] [PATCH v2] Makefile: Fix unnecessary re-patching with coreutils-9.0

"sum" command in coreutils-9.0 (e.g. Fedora 36) started to output a file name. As a result, "make" always detects a change of gdb-10.2.patch wrongly and re-applies it unnecessarily. Use standard input to fix it and "md5sum" to improve detection.
