Ok, thanks, what about this?

    # LOG_REPORT: report the test results
    LOG_REPORT   := awk '/\[OK\][\r]*$$/{p++} /\[FAIL\][\r]*$$/{f++} /\[SKIPPED\][\r]*$$/{s++} \
	                 END{ printf("%d test(s) passed, %d skipped, %d failed.", p, s, f); \
	                 printf(" See all results in %s\n", ARGV[1]); }'

    run-user: nolibc-test
	$(Q)qemu-$(QEMU_ARCH) ./nolibc-test > "$(CURDIR)/run.out" || :
	$(Q)$(LOG_REPORT) $(CURDIR)/run.out

    run: kernel
	$(Q)qemu-system-$(QEMU_ARCH) -display none -no-reboot -kernel "$(srctree)/$(IMAGE)" -serial stdio $(QEMU_ARGS) > "$(CURDIR)/run.out"
	$(Q)$(LOG_REPORT) $(CURDIR)/run.out

    rerun:
	$(Q)qemu-system-$(QEMU_ARCH) -display none -no-reboot -kernel "$(srctree)/$(IMAGE)" -serial stdio $(QEMU_ARGS) > "$(CURDIR)/run.out"
	$(Q)$(LOG_REPORT) $(CURDIR)/run.out

Or we directly add a standalone test report script? something like
tools/testing/selftests/nolibc/report.sh

    #!/bin/sh
    #
    # report.sh -- report the test results of nolibc-test
    #
    
    LOG_FILE=$1
    [ ! -f "$LOG_FILE" ] && echo "Usage: $0 /path/to/run.out"
    
    awk '
        /\[OK\][\r]*$$/{ p++ }
        /\[FAIL\][\r]*$$/{ f++ }
        /\[SKIPPED\][\r]*$$/{ s++ }
    
        END {
            printf("%d test(s) passed, %d skipped, %d failed.", p, s, f);
            printf(" See all results in %s\n", ARGV[1]);
        }' $LOG_FILE

And use it like this:

    LOG_REPORT           = $(CURDIR)/report.sh

Best regards,
Zhangjin
