bug#20733: coreutils build problem

[Michael Felt]

I assume the error is mine, but I do not understand what.

After automake and autoconf (just to be sure) make wants to call "missing", but that does not succeed.

CDPATH="${ZSH_VERSION+.}:" && cd . && /bin/sh /data/prj/gnu/coreutils/coreutils-8.23.211-b1d1a/build-aux/missing aclocal-1.15 -I m4

Yes good point.

Also it's best only worry about warnings when cross compiling,
as otherwise we're using a direct runtime check.
Updated patch is attached.

thanks,
