[U-Boot] [PATCH 1/1] x86: qemu: do not build car.o with start64.o

[Heinrich Schuchardt]

car.o can only be used with start.o, not with start64.o.

So on qemu 64bit it should only be built for 32bit SPL but not for u-boot.

Without this patch but with an unrelated pending patch
("x86: Add 64-bit setjmp/longjmp implementation") the
following error occurred for qemu-x86_64_defconfig:

arch/x86/cpu/built-in.o: In function `car_init':
arch/x86/cpu/qemu/car.S:25: undefined reference to `car_init_ret'
