I can't remember why we wanted to remove these flags in the first
place: I think it was so they would be compiler-independent, but we
also look up which compiler to use, so that shouldn't be a problem.

Does completely removing the line starting "conf_value=`echo ..."  work?

If we do need to remove some flags, we could remove an argument after
each flag if it is present.
