Let the user specify CPPFLAGS
This complements the work done in d4928ed, allowing the user to specify the preprocessor flags with the CPPFLAGS environment variable. This is useful for example to specify preprocessor macros with -D. CFLAGS could be used instead, but CPPFLAGS is more correct and is expected to be honored in some cases. For example, the helper scripts to build Debian packages make use of CPPFLAGS, but the variable is currently being ignored unless manually appended to CFLAGS.
