  I just built several GCCs from the same snapshot and in every case the
build-libiberty was produced ok. My build system was RedHat 7.1 with 7.2
and 7.3 stuff used as the update material...  So you should double-check
the '$build/libiberty' subdir, look at the 'config.log' for any possible
failure, do a 'make distclean' there, try to reconfigure only there and
then try to rebuild. Without the 'config.log' it is hard to tell what
went wrong....

  Despite of this, the 'libiberty.a's for the 'host' (and 'build' in
Canadian Crosses, gcc-3.2.x had a serious bug here) system should be 
produced...
