description:
Make running this test conditional on the setting of atf configuration
variable "run_popcount".  This is a really long-running test (it takes
several hours on a qemu-emulation on a 2.8GHz AMD Pheno II) but could
still be useful if you want to run it manually, with the command

        atf-run -v run_popcount=YES
