[PATCH] Fix the name of the qemu-system-* executable

[Dario Faggioli <dfaggioli@suse.com>]

From: Vasiliy Ulyanov <vulyanov(a)suse.de>

Define the target machine architecture in lowercase.

The name of the executable qemu-system-* is defined from the build flags
and should be in lowercase:

    ( "qemu-system-" ARCH ),

I.e. qemu-system-x86_64 instead of qemu-system-X86_64. Otherwise, the
exec call will fail.
