Hi Stefano,
Thanks for the report.
It would help to know why strace reported no matches.
Maybe it's due to alternate names like stat64?

If you apply the following patch and rerun that test,
it should provide that information:

    make check -C tests TESTS=ls/stat-free-color VERBOSE=yes

If my guess is correct, then adding ",stat64,lstat64"
to the strace command may be the solution:

   strace -o log -e stat,lstat,stat64,lstat64 ls --color=always . || fail=1
