[PATCH] JDK-8167368 Leftover: get_source.sh in build documentation

[Sergey]

Hi,

I'm not sure if that's the right mailing list, however, I'll try.
Recently, when I was taking a closer look at build documentation:
* doc/building.html
* doc/building.md

I've noticed there get_source.sh being mentioned. I believe that's a
leftover of JEP-296 Consolidate JDK Forest into a Single Repository.
I've made a trivial patch and want to contribute it. Please find it inlined
below.

Thanks,
Sergei

 <p>Here are a suggested list of things to try if you are having unexpected
build problems. Each step requires more time than the one before, so try
them in order. Most issues will be solved at step 1 or 2.</p>
 <ol type="1">
 <li><p>Make sure your forest is up-to-date</p>

version of all repositories.</p></li>

all repositories.</p></li>
 <li><p>Clean build results</p>
 <p>The simplest way to fix incremental rebuild issues is to run <code>make
clean</code>. This will remove all build results, but not the configuration
or any build system support artifacts. In most cases, this will solve build
errors resulting from incremental build mismatches.</p></li>
 <li><p>Completely clean the build directory.</p>
