Since bit 5 is set, I think that means the processor was expecting
Thumb instructions, which at least explains the error.
To confirm that it's some bad jump or mismanagement of the mode by the
Racket JIT, does changing "racket/src/lightning/arm/asm.h" to disable
Thumb support allow the build to work?
