Prerelease is not a treat on ia64 (at least older ia64 systems)

Just got a failure.

This release will not bootstrap on an ia64 system running Red Hat
AW 2.1, because of the (known) libunwind problem.

The genmodes program is built by the stage 1 compiler, and then fails
to run, because while a libunsind.so.7 was also built, it is not on
the path.  So, we get

./genmodes -h > tmp-modes.h
./genmodes: error while loading shared libraries: libunwind.so.7: cannot open shared object file: No such file or directory
