Message:

Merge partial Clang reviving

Merge from lp:~vojtech-horky/helenos/misc revives Clang support for ia32
and amd64 - it is possible to compile HelenOS with Clang 3.2 again. The
created image fails to boot, though. For ia32, the problem is probably
in some HID driver, with amd64 it crashes before reaching GUI, still do
not know why.

Merging also minor improvement to ew.py - do not use KVM when running
amd64 on 32-bit host.
