I don't normally use glibc toolchains for embedded, but I believe you
only have those if you built glibc with --enable-static-nss. By default
glibc will dlopen libnss instead (to handle dynamic name resolution).

Those should get removed at the end through the target-finalize step in
the toplevel Makefile unless you have BR2_HAVE_DEVFILES enabled.
