If someone wants to disable assert()s, he uses the option -DNDEBUG, and
according to the autoconf manual [1]
   "If a compiler option affects only the behavior of the preprocessor
    (e.g., -Dname), it should be put into CPPFLAGS"
this option belongs in CPPFLAGS.

But just because guile has been built with assertions turned off, doesn't
mean that every program that uses guile wants to disable assertions. So
this is a second reason to put only -I options from $CPPFLAGS into
guile-2.0.pc.
