RFR: JDK-8176509 Use pandoc for converting build readme to html

[Erik Joelsson]

Hello,

Nice to see this handled by make.

In UpdateBuildDocs.gmk, the test for PANDOC can be moved out of the 
macro body and just be executed once. In the recipe, you call 
CheckLineLength, which I don't see defined anywhere, but then the logic 
just after the call looks like what would be the implementation.
