This mitigates following issues during u-boot do_compile() step --
otherwise, if comm is not available, they are quietly ignored:
.../scripts/check-config.sh: line 33: comm: command not found
.../scripts/check-config.sh: line 39: comm: command not found
Since 'comm' is provided by coreutils package, adding it to HOSTTOOLS
was considered a lower impact fix compared to adding coreutils-native
buildtime dependency to u-boot recipe.
