Force --with-optim and --with-port to have argument values, since

Force --with-optim and --with-port to have argument values, since
they result in later compile errors otherwise.

I would have removed --with-optim in favor of just setting it with
an environment variable, but then it wouldn't be saved in config.nice.
A better solution is needed because these arguments can only accept
a single value (quotes and spaces are stripped).  Perhaps setting
OPTIM within config.nice?  First things first.
