Thanks for the report.

However, "make installcheck" is a no-op for most packages.  Besides,
it would not be useful to coreutils, unless you use a non-default
configuration that would install su, which is normally set-UID (su
is not normally installed).  In other words, "make check" is just fine,
since none of these programs act differently depending on whether they
are installed or in the build directory.
