I don't know if you can get this information from a running binary
kernel.   But you can always keep the .config file from /usr/src/linux,
this stores your compile options.  Simply copy the .config from the root
of one kernel source tree to another, and then run it's config utility.
Even with .config you MUST MUST MUST run the config utility (make
menuconfig, make xconfig, whatever....) but you can simply save/exit as
this will update .config for whatever new/changed parameters exist.  I'm
assuming an older -> newer or same -> same kernel trees,  it may not
work going newer -> older.  When I checked I thought the RH source RPMs
contained the .config file,  but that was along time ago.
