No.

There's some things that can be done to make this process easier.
However, there are four kinds of ports: simple, host tools needed and
no cross support, with broken cross support, with working cross
support.

Only the first and the last can work.  The last works by telling
config to use its cross config to build.  The first works by telling
it to use ALL tools for cross build.

I have a bunch of patches to install the cross tools into
/usr/arm-freebsd so that autoconfig for the working ports can work,
and a string of CC=, LD=, etc can work for the simple ports.  I've not
had time to integrate those into the tree yet.  I also have some
half-assed patches to ports as of about 4.8 that can help a little,
but that don't apply cleanly to present ports...
