[rb-general] [PATCH] docs/buy_in: Document improved dev speed

[Clemens Lang]

From: Clemens Lang <neverpanic at gmail.com>

We all like faster builds due to caching if some output did not change
and thus not require dependent tasks to be re-run. That stuff saves some
companies a significant amount of money, so that's a selling point we
should have.

+Increased Development Speed
+---------------------------
+Dependent packages do not need to be rebuilt and dependent tasks do not
+need to be rerun if a rebuild of a package does not yield different
+results. This can significantly reduce build times and lead to faster
+development speeds and lower cost.
+
+Build speeds can also be improved by showing that cross-compilation
+produces the same result as native compilation and then doing the
+mojority of builds with cross-compilation on faster machines.
