Well I used this sed, except I changed 486 to 686, and everything built 
successfully. Checking the logs, the Glibc build system doesn't seem to 
make use of g++ or c++ anywhere, so the change to CXXFLAGS seems 
harmless. The advantage of the above is that it is shorter, but the 
advantage to Dan's original is that it is obvious we are adjusting the 
CFLAGS variable. Of course, that can always be explained in notes, too.

Anyone have a preference? I'd like to get Matt's patches and this change 
into trunk today, if possible.
