Thanks, pushed.

I never used autobuild.sh, but it shouldn't do any thing different
than a manual build.

I know of this two symbols (virCondWaitUntil and virPipeReadUntilEOF)
and am right now preparing a patch to fix that. Previously I just
removed virCondWaitUntil and virPipeReadUntilEOF from the symbol

I never had problems with the other two symbols:
linuxDomainInterfaceStats and xenLinuxDomainBlockStats

I build directly on Windows instead of cross-compiling from Fedora,
maybe that makes a difference.
