The change "fix hostname conflict with other packages" moved the
hostname util to the list of base_bindir_progs, so do_install_append()
now expects hostname to have been built.
coreutils do_install_append() is shared between target and nativesdk
builds (though not used by native build, see comment) so hostname should
be enabled to build on both of them.
