I've tried to build an egcs snapshot, egcs-980115 via make bootstrap, without
setting the prefix, and it failed.  It complained like this:

Is there a version that does NOT do this?  Or, is this the version of choice
and I am witnessing
an incompatibility with my native compiler libraries?

The compiler is gcc 2.7.2.1, binutils-2.6.0.15.  I have not requested that
newlib is used at this point.
Should binutils also be updated? I think 2.8.0.1.23 is latest.
