This patch leads to a build error when building with

In file included from include/configs/qemu-x86.h:23,
                  from include/config.h:5,
                  from include/common.h:23,
                  from lib/asm-offsets.c:14:
include/configs/x86-common.h:109: error: "BOOTENV" redefined [-Werror]
  #define BOOTENV

In file included from include/configs/qemu-x86.h:22,
                  from include/config.h:5,
                  from include/common.h:23,
                  from lib/asm-offsets.c:14:
include/config_distro_bootcmd.h:407: note: this is the location of the
previous definition
  #define BOOTENV \

I am glad that qemu-x86 now can use distro defaults. But I would not
expect a build error due to a legal configuration choice.

If you do not want to retain backwards compatibility you could 'select
DISTRO_DEFAULTS' in board/emulation/Kconfig. This way distro defaults
would no longer be deselectable for qemu-x86.

Best regards
