You have to convert your code/system to use the EABI version of GCC; or you
have to modify your source so that it doesn't use volatile bitfields.  The EABI
for ARM mandates the behaviour of volatile bitfields, but the arm-elf
configuration does not use that ABI and has different semantics in this area.
