yocto-bsp: runqemu runs beaglebone-yocto

Browse Source 
Append the necessary QB_ flags to the MACHINE configuration of
beaglebone-yocto. Using Qemu with "-machine virt" simplifies things
greatly because for this machine the dtb is compiled into qemu. Since
the beaglebone-yocto kernel config also supports this cpu architecture,
it just works. However, u-boot is not involved and the virt machine is
not 100% equal to a am335x SoC.

A MACHINE configuration suitable for Qemu as well as for the real
hardware allows to provide just one eSDK where both runqemu and devtool
build-image work. Otherwise a qemuarm and a beaglebord-yocto MACHINE
eSDK would be required to support development in Qemu as well as on real
hardware.
