[Cbc] cbc configure --prefix= option install for RPM inclusion

[Ted Ralphs]

This looks like an easy fix. The test that is causing the error is
unnecessary and can just be eliminated. To propagate the change to all
configure scripts in all dependent projects and out to release is going to
take a while and we'll have to do some testing first.

In the meantime, though, I realized that the error does not cause the
configure script to fail for me---I just get the message and configure goes
through anyway. In this case, everything should be fine and you can make as
usual. If the error is causing the script to stop, then maybe you are
running with "set -e"? If so, just not doing that should allow things to go
through for now.

Alternatively, this should patch the scripts so that you don't get the
error:

for i in `find . -name configure`; do sed 's/full_prefix=`cd $full_prefix ;
pwd`//' $i > xxx; mv xxx $i; done

Let me know if this is good enough for now and I'll try to get that fix out
as soon as I can get it tested.
