PATCH 1/1 scripst/runqemu: Allow to use qemu from host.

From: Mariano Lopez <[email protected]>

This will add support to use qemu from the running host, with this is possible to put qemu-native in ASSUME_PROVIDED variable.

By default it will try to get qemu from the build sysroot, and only if it fails will try to use the host's qemu.
