In D12421, the ability to compile stand/ in little-endian was added, with the intention to extend loader.kboot to run in Petitboot.
However, no further work was done, as the kernel then gained self-execution capabilities as Petitboot was taught to load FreeBSD kernels directly.
The FreeBSD installer on powerpc64 (on POWER8 and POWER9) uses /boot/etc/kboot.conf instead of loader.
As this option does nothing but cause stand/ to be miscompiled and actively causes confusion, remove it.
(I have a functioning petitboot loader in my local tree, however, it turned out to be quite inconvient to use due to the current petitboot plugin design so I put it on hold.)
