[PATCH] Refactor duplicate functions

[Bernard Ogden]

  I'm not altogether sure about adding the 'arm' namespace in Tools. The intent of these functions is that they can be used by _any_ arm-targetting toolchain, rather than being limited to some arm-specific toolchain. So possibly I'm breaking with the intent of this file.

  If not, we get to eliminate two duplicate functions, which would be nice.
