That did not help, but after I changed this:

~/kvm-userspace$ diff configure.old configure
95,96c95,96
< #set kenel directory
< libkvm_kerneldir=$(readlink -f kernel)
---
 > #set kernel directory
 > libkvm_kerneldir=$(readlink -f $kerneldir)

the error was gone. configure used kvm.h in /usr/include/linux/ (distro 
suplied 2.6.27 headers) instead of the git version.

My troubles aren't totaly gone however:
