Two, unrelated patches intermerged (sorry)

o Add support for TARGET_ARCH=armv6.  This is just the compile phase
  and hasn't done things like get uname to return armv6.
o Add support for external compilers:
  - Define EXT_COMP to be the prefix to prepend to the normal
    commands (either the full path or just armv6-freebsd-)
  - Some things don't work: KERBEROS and RESCUE.

To test it out:
o sudo make xdev XDEV=arm XDEV_ARCH=armv6
o make buildworld WITHOUT_RESCUE=y WITHOUT_KERBEROS=y TARGET=arm TARGET_ARCH=armv6

Things missing:
o We still build some tools we don't need to.
o Really need to have a SYSTEM_COMPILER={gcc,clang,external} to make this
  nicer.  In fact, we may need gcc42, gcc43, etc to get the warnings flags
  right (or GCC_VERSION and CLANG_VERSION).
o crunchgen is busted in this configuration.  I fixed one thing, but it
  needs more love for rescue to work.  Also, it likely just needs to be
  a bootstrap tool again, and the test needs to include a freebsd version
  bump.
o External toolchains, like those delivered by the chip vendors, have not
  been tested.  There's likely tweaks needed.
o It assumes that the standard tools are called the stanard things.  This
  isn't true, afaik, with externally built clang without symlinks.

It is 'stage 2' in my roadmap:
o stage 1: cross build kernels with minimal effort
o stage 2: cross build with xdev built compilers
o stage 3: cross build with external gcc compilers
o stage 4: cross build with external clang
o stage 5: profit.
