[patch] gdbarch.sh, only print macro when defined

[Andrew Cagney <ac131313 at cygnus dot com>]

FYI,

I've committed the attached.  It, firstly prints the value of
GDB_MULTI_ARCH (more useful than you may expect) and secondly makes all
the macro's printed in gdbarch_dump conditional on their definition.

	* gdbarch.sh (gdbarch_dump): Print the value of GDB_MULTI_ARCH.
  	Always check that a macro is defined before printing it.
	* gdbarch.c: Re-generate.
