This allows me to experimentally break stuff without having to check it in first. It also give me a way to build bootable images for when (not “if”!) I mess things up properly on the RPI. It has the advantage also of being quicker than the usual release build.

Clang has an equivalent -ffixed-r9, but the u-boot that is  mandated for FreeBSD/Arm/RPI use doesn’t have the R9 fix.

I’d be tempted to do "make xdev -DWITHOUT_CLANG -DWITH_GCC”
