uutils-coreutils: disable stdbuf compilation

There is a bug in uutils-coreutils causing stdbuf to include the HOST version of libstdbuf.so, even when cross-compiled.
As a side-effect, the uutils-coreutils binary was containing the buildpath, because RPATH was set on libstdbuf.so.
Thus the buildpath error can be re-enabled.

This is tracked upstream by https://github.com/uutils/coreutils/issues/6591
