Oh cute.

Well, that really screws up whatever I was (half-) thinking, then.

Still, though: never mind.  :-)

Even if you install as root, I assume.

The pkg-user hint already has a workaround for this in chapter 5 (a
simple copy of src/su to /usr/bin -- which should probably pay attention
to the umask or use install to explicitly set permissions, but oh well),
but the hint does nothing in chapter 6.  (Because the su installed by
coreutils would prevent shadow from installing its version, and the LFS
book currently uses the su from shadow.)  So "not installing su when a
normal user runs make install" was a good thing for that hint anyway, in
chapter 6.

Of course the real LFS book builds everything as root in chapter 6
anyway, so (I assume) even then shadow won't copy over the coreutils su.
But it's only an issue if we want to use the coreutils su -- if not,
then having coreutils avoid installing su is actually slightly good.  It
won't get overwritten later, and it won't overwrite shadow's su if you
have to reinstall coreutils.
