ref-manual: Updated text for speeding up builds.

The "Speeding Up the Build" section presents a list of items the
user can consider when they want to tweak the build speed.  One of
the items is the three variables BB_NUMBER_THREADS, BB_NUMBER_PARSE_THREADS,
and PARALLEL_MAKE.  It was noted that the system figures out
the optimal settings for these now and it is pretty useless to
override the settings.  However, the introducing sentence to the
list is still valid due to other considerations that go beyond these
three variables.  So, to update the text, I have re-emphasized the
role of these three variables for quickening the build time.

As previously mentioned, the build system scales the values
for these variables.

for these variables so you should probably not override
these to try to speed up a build.
However, for completeness regarding this list, it is worth
mentioning that you can manually override these variables
