If the CONFIG_USE_DEFAULT_ENV_FILE=y and CONFIG_DEFAULT_ENV_FILE
points to the empty environment file, the auto-generated file has
wrong syntax so it leads to the compilation failure:
In file included from include/env_default.h:115,
from env/common.c:29:
include/generated/defaultenv_autogenerated.h:1:1: error: expected expression before ‘,’ token
1 | , 0x00
| ^
make[1]: *** [scripts/Makefile.build:266: env/common.o] Error 1
make[1]: *** Waiting for unfinished jobs....
make: *** [Makefile:1744: env] Error 2
Fix this issue conditionally adding the delimiter ", ".
