    libffi/x86: Always check __x86_64__ for x32 hosts (#601) (#602)

    Since for x86_64-*x32 and x86_64-x32-* hosts, -m32 generates ia32 codes.
    We should always check __x86_64__ for x32 hosts.

Since for gnux32 hosts, -m32 generates i386 codes, always check __x86_64__
for x86 hosts.

	PR libffi/101336
	* configure.host: Always check __x86_64__ for x86 hosts.
