Try using
CPPFLAGS+= -isystem${LOCALBASE}/include
gcc(1) (and clang) has a flag for systems broken by design:
-isystem dir
Search dir for header files, after all directories specified by -I
but before the standard system directories. Mark it as a system
directory, so that it gets the same special treatment as is applied
to the standard system directories. If dir begins with "=", then
the "=" will be replaced by the sysroot prefix; see --sysroot and
-isysroot.
For example, firefox uses it to avoid picking up lang/spidermonkey headers.
