It's needed when bootstrapping glibc, ie. if you don't have a previous
libc and crt* files available. The trouble is that building a shared
glibc requires crt* to build, and the glibc build machinery isn't
clever enough to pick up newly built crt* files. Also, gcc's configure
makes use of AC_TRY_LINK, which again needs crt files. :-(
