patch: honor CPPFLAGS in Make.rules

[Todd Vierling]

Nearly all autoconf-based programs use CPPFLAGS to indicate flags to pass to
cc for compilation and/or cpp for preprocessing.  This is different from
CFLAGS, which is intended for optimization and debugging flags specific to
compiling.  It's even listed in "./configure --help".

The following will make the Wine build honor CPPFLAGS if set during
configuration:
