Okay, I've finally confirmed this all the way to completion, the
correct way to update an existing armv6hf system to the new armv6 that
is hardfloat by default is to add TARGET_ARCH=armv6 to the make command
line for *both* the build and install steps.

I started with a fresh armv6hf system built from r300118, then updated
to r300438 and built kernel and world with TARGET_ARCH=armv6.  Then to
install I took a bit of a shortcut over the normal freebsd update
procedure and just did:
  
  make DESTDIR=/ TARGET_ARCH=armv6 KERNCONF=IMX6 installkernel
  init 1
  <then in single-user mode>
  cd /usr/src
  make DESTDIR=/ TARGET_ARCH=armv6 installworld  
  reboot

I'm not recommending anyone else shortcut their normal update procedure
(mergemaster, all that stuff); I'm mostly trying to make sure this
crossbuild stuff creates a bootable system, then I'm just going to
erase it all.

Most folks should just do whatever they normally do to update, but add
TARGET_ARCH=armv6 to all make commands when updating an armv6hf system.
