use_default_rpm_opt_flags. It defaults to a value of 1, meaning that we'll try to use $RPM_OPT_FLAGS. But if you're not compiling with the GNU compilers, you might want to set this value to 0 so that your compiler doesn't get flags that it doesn't understand (e.g., PGI 7.0 will barf on flags that it doesn't understand).
