In the preceding commit the discussion of the *_SHA1 knobs was left as-is to benefit from a smaller diff, but since we're changing these let's use the same phrasing we use for most other knobs. E.g. "define X", not "define X environment variable", and get rid of the "when running make to link with" entirely.

Furthermore the discussion of DC_SHA1* options is now under a "Options for the sha1collisiondetection implementation" heading, so we don't need to clarify that these options go along with DC_SHA1=Y, so let's rephrase them accordingly.
