Hi!

Prior to r203634 we were comparing TARGET_64BIT with
ix86_isa_flags & OPTION_MASK_ISA_64BIT, which is the same thing for
TARGET_BI_ARCH, otherwise the former is hardcoded constant.
But with r203634, the condition was changed and is now always false
and so e.g. for 32-bit non-multilib i?86 gcc we don't complain about
lack of -m64 support anymore, instead just ICE later on.

Fixed by making TARGET_64BIT_P that the new condition tests also
constant for !TARGET_BI_ARCH.

Bootstrapped/regtested on x86_64-linux and i686-linux, ok for trunk?

	PR target/60610
	* config/i386/i386.h (TARGET_64BIT_P): If not TARGET_BI_ARCH,
	redefine to 1 or 0.
	* config/i386/darwin.h (TARGET_64BIT_P): Redefine to
	TARGET_ISA_64BIT_P(x).
