I see, you nailed it down already.

The concept of "expected failure" fits here, I think. If the test suite would flag
this as an XFAIL rather than a FAIL, people would not report it.

AFAIU from the doc [1], the way to turn a FAIL into an XFAIL is to add something
like this in the Makefile.am:

  XFAIL_TESTS =
  if $host is x86_64-*-linux* and $HOST_CPU_C_ABI is i386
  XFAIL_TESTS += timestamp
  fi
