In the command explanation section it has the following note:

I found that just having CC=gcc was not enough to get this to correctly build,
as for some reason the build would still try using clang to, if I have the term
correct, linking, ie using clang
equivalent of g++
This was not my doing. I am just following what is currently listed in svn for
the instructions for both systemd version and for sysv of the book.

FWIW, I've been using both CC=gcc CXX=g++ in my Cups build for quite some time,
for the very same reason mentioned by Christopher.
Looking back at my history, it was at the time when -DLLVM_LINK_LLVM_DYLIB=ON
was added to llvm.

I don't dny your experience, but I have in my logs/scripts:
Fri May 11 20:34:12 CDT 2018 /usr/src/llvm/llvm-6.0.0.src.tar.xz
Tue May 15 16:10:10 CDT 2018 /usr/src/cups/cups-2.2.7-source.tar.gz
CC=gcc \
./configure --libdir=/usr/lib \
--disable-systemd \
--with-rcdir=/tmp/cupsinit \
--with-system-groups=lpadmin \
--with-docdir=/usr/share/cups/doc-$VER
For llvm I do have -DLLVM_LINK_LLVM_DYLIB=ON
In my cups build log I have:
Using CC=gcc
Using CXX=gcc
In my build directory, there are no .cc or .cpp files.
I cannot duplicate the issue.
You might want to run 'make --trace' to get a verbose listing to see
what is happening.
Also take a look at the Makedefs file. The relevant definitions I have
does have CXX = clang++ and DSOXX = $(CXX) and LD_CXX = $(CXX). There
are some cxx files in the scheduler/ and ppdc/ directories.
I do note that my build log also has:
Compiling cups-driverd.cxx...
warning: unknown warning option '-Wno-format-truncation'
[-Wunknown-warning-option]
But that didn't break the build for me.
