Yes, sadly this is an unfortunate interaction between Apple's linker
and autoconf.  You might be able to fix it by installing a very recent
version of autotools and regenerating all the autoconfigury for each
"subproject" that nestedvm imports, but it's messy.

Personally, I think Apple needs to do something about it.  Rebuilding
all the ./configure scripts out there just isn't practical -- Apple
needs to provide an environment variable that turns off this behavior.
