For recent (gcc-3.2 or later) compilers, it should be ok
to move after building (there is a slight risk of the
original paths being referenced, but in practice this seems
to not matter).

See http://kegel.com/crosstool/crosstool-0.28-rc37/doc/crosstool-howto.html#canadian
(including the note at the bottom of that paragraph) for
more about cross-building compilers (i.e. "canadian cross compilers").
See also demo-canadian.sh in the crosstool directory.

I haven't checked out Steven Magnani's work yet, so I can't comment on it,
but it's nice to see somebody else trying to make canadian crosses easier.
