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
