This is an all-in-one fix for the smaller and bigger mistakes of the
build system changes for accompanied Linux headers:
 - only enable KVM and vhost on Linux hosts
 - fix powerpc asm header symlink
 - do not use Linux headers on non-Linux hosts
 - fix kvmclock for !CONFIG_KVM
 - fix s390 build on non-Linux hosts

Let me know if separate patches are preferred for this.

Builds okay on Darwin/ppc64.
