This is no solution since you have no control over the place where the
parameter is used relative to whatever you try to disable.  CPPFLAGS
handling in configure is only there because that's the default.  If
you have to work around broken environments you have to have more
control.  Complicating the makefile handling even more without any
real benefit doesn't really sound right.
