lang/gcc* search under LOCALBASE/include implicitly e.g. ports/136917.
This enables --with-expat automatically when its headers are found.

  $ gcc45 -E -v -</dev/null
  ignoring nonexistent directory "/usr/local/include"
  ignoring nonexistent directory "LOCALBASE/lib/gcc45/.../include"
  #include "..." search starts here:
  #include <...> search starts here:
  End of search list.

Can you try to replace -I${LOCALBASE}/include with
-isystem${LOCALBASE}/include ? It should make GCC prefer ./../bfd/bfd.h
over LOCALBASE/include/bfd.h.
