LilyPond Contributor's Guide: 10.8.7 Verify successful build

### 10.8.7 Verify successful build

When the changes have been made, successful completion must be verified by doing

>     make all
>     make doc

When these commands complete without error, the patch is considered to function successfully.

Developers on Windows who are unable to build LilyPond should get help from a Linux or OSX developer to do the make tests.
