Applied to master, after doing the following change:

    [Thomas: add BR2_PACKAGE_HOST_TI_CGT_PRU_ARCH_SUPPORTS boolean option,
    so that packages selecting host-ti-cgt-pru can easily inherit its
    architecture dependencies.]

Also, could you send a patch that adds yourself to the DEVELOPERS file
for both the ti-cgt-pru and the pru-software-support packages?

Thanks!

Thomas
