It seems that this is not a good idea since once we add the following line,
it would cause all the target recipe's do_package depends on
base-passwd:do_populate_sysroot, this would cause the arch "all" depends on
eglibc since base-passwd depends on eglibc, we may need fix in another way.

do_package[depends] += "base-passwd:do_populate_sysroot"
