GNU's core tools were built with non-GNU stuff like Vim and valgrind, but you don't see them getting special mention either. And much of the modern userland requires, say, Python to function! No mention there, either. The idea that part of the userland deserves a special mention (but no, not the rest, just GNU) is over-privileged attention-seeking.
The convention has generally become that Linux-kernel operating systems are called "Linux". But you have options if this offends you so. If you don't like that, Debian's over there and willing to play along, and if you really don't like it, I hear that GNU has a kernel of their own rattling somewhere around gnu.org.
