Run 'make menuconfig'. Once in it, hit / to get a search box.
Enter GENERIC_CALIBRATE_DELAY (or a substring of that). Hit enter, and
enjoy. :)
Symbol: GENERIC_CALIBRATE_DELAY [=y]

That's not very helpful.
% find . -name 'Kconf*' | xargs grep GENERIC_CALIB
./lib/Kconfig.debug: depends on DEBUG_KERNEL && PRINTK &&
GENERIC_CALIBRATE_DELAY
./arch/metag/Kconfig:config GENERIC_CALIBRATE_DELAY
./arch/sh/Kconfig:config GENERIC_CALIBRATE_DELAY
(and lots more).
Turns out it's basically a flag for "This arch is able to support
the BOOT_PRINTK_DELAY option"....
