configure: Don't let autoconf pick our CFLAGS

If the user hasn't specified CFLAGS on the command line to
./configure, then autoconf will set them to -g -O2 if the compiler
supports those options.

For compatibility with what OpenAFS has always done, and to let us
manually set optimisation and debugging flags later, disable this
behaviour.
