Removing src/backend from include path might break on HPUX

Now that we don't -I...backend anymore, this might break:
src/include/c.h:

#ifdef FIXADE
#if defined(hpux)
#include "port/hpux/fixade.h" /* for unaligned access fixup */
#endif /* hpux */
#endif

The comments surrounding this make it pretty unclear whether this is still
necessary. Tom, any idea?

FIXADE is not defined on the normal HPUX build, so it's a non-issue as
far as I know. AFAICT this file dates back to Berkeley days and exists
only to work around HP compiler bugs that existed about ten years ago.
We don't support HPUX <= 9.01 anymore anyway; there are plenty of other
reasons not to.

I have been planning for some time to nuke fixade.h, but haven't got
round to it. Be my guest (and don't forget to zap the reference to it
in src/backend/Makefile's install stuff too. AFAICT we don't need to
make an installed include/port subdirectory at all anymore...)

BTW, there are a couple of other templates that define NOFIXADE, which
seems to be something completely different; don't mistake it as being
the inverse of FIXADE.
