RFR: 9/8u40 8062475: Enable hook for custom doc generation

[Erik Joelsson]

Hello Roger,

I JDK 9 we introduced a macro call that handles custom inclusion instead 
of directly doing -include. Look for example in make/common/MakeBase.gmk.

# Hook to include the corresponding custom file, if present.
$(eval $(call IncludeCustomExtension, , common/MakeBase.gmk))

Our definition of the macro can be found in custom-spec.gmk. It will 
refrain from including if --enable-openjdk-only is specified to configure.

In JDK 8, your patch is correct, but there you need to guard the 
contents of the custom Javadoc.gmk with "ifndef OPENJDK".
