Currently CONFIG_REORDER uses -ffunction-sections for all code;
however, creating a separate section for each function is not useful
for modules and just adds bloat.  Moving this option from CFLAGS to
CFLAGS_KERNEL shrinks module object files (e.g., the module tree for a
kernel built with most drivers as modules shrinked from 54M to 46M),
and decreases the number of sysfs files in /sys/module/*/sections/
directories.
