Fix fallouts from Linux header inclusion
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 Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Tested-by: Andreas Färber <andreas.faerber@web.de> Tested-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
