 Sounds like an extra header on all functions for which we'd pay a size
 price, while the current maverick armel binaries are all Thumb.  Isn't
 this specific to your use case?

 This sounds like a missing implementation rather than just a toolchain
 flag; or perhaps it's not needed at all with AAPCS?
