The ABI stability check code needs to be implemented.

The copy function needs to be impelemnted too (I didn't check next patch
thoug yet)

I've looked through the next patch and you don't parse any device info
for the CPU type. Is it necessary to have it present at all in that
case?

Function declarations should be along with function definitions.

Breaks "make syntax-check" again:

Expected symbol virDomainCPUDefFree is not in ELF library

The symbols entry can be added only when the function is defined.
