Ok, it will be a further step, based on your new awk script, it is not
that hard.

This should work:

    REPORT  ?= awk '/\[OK\][\r]*$$/{p++} /\[FAIL\][\r]*$$/{f++;print} /\[SKIPPED\][\r]*$$/{s++} \
                END{ printf("\n%d test(s): %d passed, %d skipped, %d failed => status: ", p+s+f, p, s, f); \
                if (f) printf("failure\n"); else if (s) printf("warning\n"); else printf("success\n");; \
                printf("\nSee all results in %s\n", ARGV[1]); }'

It reports something like this:

    ...
    Total number of errors: 0
    Exiting with status 0

    143 test(s): 140 passed, 3 skipped, 0 failed => status: warning

    See all results in /labs/linux-lab/src/linux-stable/tools/testing/selftests/nolibc/build/x86/run.out

Two newlines are added around the summary line, so, it is not crowded as
before. If this is ok, will send a new patch on your new branch.

Thanks very much.
