Not only that, but beyond the licensing issues it's really not supported by glibc itself because glibc will dlopen NSS and iconv, which link to libc, which leads to glibc being dynamically linked anyway except now you have two copies of it, which can play havoc on shared resources (like standard streams).
It's an issue from a licensing point of view, but it's also a rather poor idea from a technical point of view.
"You" here is a generic pronoun, not "you, reader"
