ok, it looks like the only way to use the cross build tools is to have
ALT_COMPILER_PATH set, with the assumption that this has to be separate path
than the one for the host tools.  On Debian/Ubuntu these tools are located in a
common path, /usr/bin, and I don't see a way to explicitly set the *name* for
the target tools.  Would it be possible to add macros at any location where one
of the host tools gets defined? like

  HOST_CC = $(host_prefix)gcc
  CXX = $(target_prefix)gcc

Or should another approach be used?
