description:
* Add -march=armv5, -march=armv5t, -march=armv5te, which are internally
  treated like -march=armv4t, but which generate __ARM_ARCH_5__,
  __ARM_ARCH_5T__, and __ARM_ARCH_5TE__ defines, respecitively.
* Add -mcpu=xscale, which is internally treated like -mcpu=strongarm,
  but which generates __ARM_ARCH_5TE__ and __XSCALE__ defines.

These command-line options and definitions are consistent with gcc 3.x,
and allow NetBSD Makefiles to use them in a forward-compatible way, and
also give hand-tuned source code (e.g. assembly) a chance of tuning for
XScale.
