default config-3.10 has CONFIG_HW_RANDOM=y and CONFIG_HW_RANDOM_BCM63XX=y.
You run make kernel_menuconfig and deselect CONFIG_HW_RANDOM. Because
CONFIG_HW_RANDOM_BCM63XX depends on CONFIG_HW_RANDOM,
CONFIG_HW_RANDOM_BCM63XX is not defined anymore, and your modified
config-3.10 now only contains "# CONFIG_HW_RANDOM is not set".
Now something in the build system selects CONFIG_HW_RANDOM=m, and
suddenly CONFIG_HW_RANDOM_BCM63XX is available again, but config-3.10
does not contain CONFIG_HW_RANDOM_BCM63XX anymore, so the kernel
config system needs to ask what you want as its value.
If you leave CONFIG_HW_RANDOM=y and only disable
CONFIG_HW_RANDOM_BCM63XX, then you will have no issue, because then
your config-3.10 will contain a line "# CONFIG_HW_RANDOM_BCM63XX is
