Paths to compiler, binutils etc. in 4.5.0 beta 3 build

[Nick.SIMON at syntegra.bt.co.uk]

Chaps,

Having decided it's safe to put beta3 on our main Linux box ('cos the spare
PC I've been using is S-L-O-W) I'm now getting all the old tools invoked,
from usr/locals/rtems/bin, instead of the shiny new ones from
/opt/rtems/bin.

Where do the CC_FOR_TARGET and so on, in the makefiles, come from?  How can
I get the 4.5 build to use the new tools without disturbing 4.0 based work?

Thanks In Advance,
