Warner Losh 8f3b60c5f1 Correct the detection of hard float arm
* Don't test MACHINE, it's irrelevant to userland and should never be
  used in userland Makefiles.
* If we match armv[67] and CPUTYPE is undefined OR it doesn't have
  'soft' in it, choose armhf.
* Add a note that the soft float on armv[67] may be broken.
