maya dbb92af837 gcc{48,49,5,6}: add patch to avoid fragile include guard logic
for ansi.h on netbsd.
gcc{7,8}: document same patch that already existed was upstreamed.

This patch is necessary to build GCC on NetBSD >= 9.0, since changes
to ansi.h resulted in not using the same include guards.

Avoid relying on fragile include guards for NetBSD ansi.h.
DragonflyBSD support
Both upstreamed (GCC 9.x, GCC 5.x respectively)
