It is with some reluctance that I am committing the following patch.  My 
reasons for doing so are as follows:

1) Building the ARM compiler has been broken because of this for over a 
month now
2) There is no apparent sign that a patch for the C++ front end is 
forthcoming from a C++ mainatiner, even though the bug lies there and not 
in the ARM back-end.
3) I have insufficient understanding of the tree system to fix the front 
end myself, or, given the anticipated time-scales for the release, time to 
acquire that knowledge.

Given that we have a major release coming up, to remain in this state is 
unacceptable.  So I've decided that we will have to disable the XScale 
builtins until such time as the problem is fixed -- at this point I 
consider being able to build and install the C++ libraries more important 
than supporting the newlib builds for Xscale (which I believe will now 
fail as a result of this).

I have tried to produce, but have been unsuccessful, a test case which 
causes a similar problem with one of the standard built-ins.  This 
probably means I still don't fully understand the failure fully.

Richard.
