The requirement for libz was removed, so up until recently we only needed
a 64bit version of elfutils which is easy to build.

It looks like we now have a requirement on binutils which is considerably
more painful to build. One option is to make the bfd requirement optional, all
you lose would be the ability to see c++ demangled names I think.
