EXTRA_LIB was keep to maintain backward compatibility, but the use of 
the APPEND_ and PREPEND_ flags should provide the same functionality 
with more flexibility (see 24141:078392e5078d).
I don't think the hypervisor needs any special libs to build, at least I 
never had to pass any extra libs to build it on the several not so 
common systems I've build Xen on (NetBSD and uClibc).
