Paolo Bonzini 66aef1c644 detect 32-/64-bit variant of i386 back-end at include time (not configure time)
2008-06-11  Paolo Bonzini  <bonzini@gnu.org>

	* build-aux/lightning.m4: Adjust LIGHTNING_BACKENDS, don't
	use suffix support to distinguish i386/x86_64.
	* lightning/i386/Makefile.frag: Use LIGHTNING_TARGET_FILES
	to distribute *-32.h and *-64.h files now.
	* lightning/i386/asm-i386: Moved to...
	* lightning/i386/asm.h: Include the appropriate subtarget file.
	* lightning/i386/core-i386: Moved to...
	* lightning/i386/core.h: Include the appropriate subtarget file.
	* lightning/i386/fp.h: New, include the appropriate subtarget file.
	* lightning/i386/asm-32: Do not include asm-i386.h.
	* lightning/i386/asm-64.h: Likewise.
	* lightning/i386/core-32: Do not include core-i386.h.
	* lightning/i386/core-64.h: Likewise.
	* lightning/Makefile.am: Adjust for renamed files.

	* configure.ac: Define LIGHTNING_TARGET here.
	* opcode/disass.c: Change list of valid LIGHTNING_TARGET values.

	* lightningize.in: Robustify against missing subtarget files.
