I'm helpless about this as well. gcc is correctly called with -ldl as we can see from the verbose output:

My main machine is a x86_64 Fedora 16 and here it's building fine using the exact same procedure...

Would you recommend qemu 0.15 or 1.0?

I had similar problems recently and the answer if was given when querying it was as follows

it's not screwed up... It's a change in GCC that requires that you do your GNU Make and other build files when linking correctly. --as-needed is turned on by default and if you're putting your .so's in front of the .o files in your link order, it skips things.

that a possible solution for you?
