According to Alan Modra alan@linuxcare.com.au, the -fno-omit-frame-pointer is

needed for x86 only. Why this used to be enabled for all architectures is beyond

me. I suspect most platforms don't need this, but until we know that for sure

I turn this off for IA-64 only. Andreas Schwab says it's also needed on m68k

to get a correct value for the wait-channel (WCHAN in ps). --davidm

config_data.h contains the same information as ikconfig.h but gzipped.

Info from config_data can be extracted from /proc/config*
