I can think of a few ways you could do this. I'm not sure which way
is best in general or for your particular needs.
You could set the CFLAGS environmental variable to -O0 or you could
set the __global_cflags or optflags definition in your rpm config (or
in the spec file or on the command line).
If you use 'CFLAGS="-O0" rpmbuild -bb package.spec' it will work,
though you won't get some of the other flags that are defined in the
%optflags and %__global_cflags by rpm. You can see what those things
default to by using 'rpm --showrc'. My i386 FC6 install has these:
optflags: %{__global_cflags} -m32 -march=i686 -mtune=generic -fasynchronous-unwind-tables
__global_cflags: -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4
Hope that gets you started in the right direction (and/or prompts
someone else here to chime in with additions and corrections :).
