x86_64 is used as a baseline: the "x86_64" entry, whatever status it has,

Uncomment TEST() and fix a minor issue by setting LC_ALL=en_US to
match the locale used upstream. All tests are OK:
Running test ./test/v0/avigomanager.sh...succeeded
Running test ./test/v0/the-feeble-files-spanish.sh...succeeded
Running test ./test/v5/CVE-2015-1386/CVE-2015-1386.sh...succeeded
