Trying to compile flashrom with a minimum number of drivers.  I'm probably just being annoying now, but I figure I might as well file bugs I find.

CONFIG_INTERNAL brings in cros_ec_i2c when compiled on arm-based architectures.  cros_ec_i2c in turn depends on CONFIG_LINUX_I2C, but that's not auto-enabled as a dependency in the Makefile.  Without it, compile fails:
