Have you tried 2.20.1 or 2.21?
I'd say if the problem still exists there, try posting something to:
http://sourceware.org/ml/binutils/

I've been building for the same architectures (ppc for e500, arm for
xscale). Granted I've been more concerned with functionality over
compile time, but next time I build, I will try comparing build times.

If you could give an example of a package you are building, I will
build the same package and compare build times. Hopefully then we can
start to dig into the problem.
