I see failures from last night on aarch64-none-elf and arm-none-eabi
(both bare-metal) configurations even after moving up to dejagnu
1.5.1. If this can't be fixed easily should we consider reverting this
patch in the interest of getting sane test results on bare-metal
targets before the release ?

Should we also update the prereqs page to say dejagnu 1.5.1 ?
