    Fix python build by using libxsltmod_la_CPPFLAGS instead of AM_CPPFLAGS
    
    Commit a2cd8a03 broke the --with-python build by moving includes from
    INCLUDES to AM_CPPFLAGS. AM_CPPFLAGS gets ignored when a target-specific
    *_CPPFLAGS variable exists, but at least some automake versions
    automatically add "libxsltmod_la_CPPFLAGS = -shared" to python/Makefile.in
