When building envtools via tools-only_defconfig the builtin defaults are based on options in the defconfig. For example:
bootcmd=bootp; setenv bootargs root=/dev/nfs nfsroot=${serverip}:${rootpath} ip=${ipaddr}:${serverip}:${gatewayip}:${netmask}:${hostname}::off; bootm bootdelay=2 baudrate=115200 stdin=serial,cros-ec-keyb,usbkbd stdout=serial,vidconsole stderr=serial,vidconsole ethaddr=00:00:11:22:33:44 eth3addr=00:00:11:22:33:45 eth5addr=00:00:11:22:33:46 eth6addr=00:00:11:22:33:47 ipaddr=1.2.3.4 bootm_size=0x10000000 kernel_addr_r=0x1000000 fdt_addr_r=0xc00000 ramdisk_addr_r=0x2000000 scriptaddr=0x1000 pxefile_addr_r=0x2000
These may or may not be sensible for any particular target. Rather than trying to have a set of defaults that work for every target add a config option to make the default environment completely empty.
