I've never got this to work reliably on either x86 or amd64 hosts. I get 
mysterious segfaults in the depths of libc. My guess is that the tricks qemu 
uses to link itself as a shared library are confusing things (possibly the 
TLS initialisation).

Configuring with --enable-static usually works around the problem.
