I haven't got a native environment set up yet.  Getting uClibc to work kind of 
cames before that on my todo list. :)

While it's possible that qemu's application emulation is good enough to handle 
emulating strace, it seems unlikely.  System emulation's definitely going to 
be up for it though, so I can build the broken version of uClibc once I 
finish the native toolchain and see what exactly's wrong with it...
