I would say printf "* $i " is portable enough.

Yes, but not due the above problems but due out-of-tree build problems.

Unfortunately $(abs_builddir) is working only when called on the top level
Makefile, which is visible in lib/newlib_tests/runtest.sh which just tries to
detect this problem:

		case $res in
			0) tpass="$tpass $i";;
			1) tfail="$tfail $i";;
			2) tbrok="$tbrok $i";;
			4) twarn="$twarn $i";;
			32) tconf="$tconf $i";;
			127) runtest_brk TBROK "Error: file not found (wrong PATH? out-of-tree build without -b?), exit code: $res";;
			*) runtest_brk TBROK "Error: unknown failure, exit code: $res";;
		esac

I'll do handling like this as well into metadata/tests/test.sh.

Kind regards,
Petr
