So far, the legal-info infrastructure was not exporting the legal
info for the C libraries. This is because the legal-info only acts
on packages defined in $(TARGETS).
But the C libraries are never added to $(TARGETS), since there is no
corresponding BR2_PACKAGE_<C-LIBRARY>.
This patch adds such symbols for the 4 C libraries we support in our
internal backend: uClibc, glibc, eglibc and musl.
