[x265] Build query...

[Ben Barker]

Ah - I've answered my own question:

One machine, which I built succesfully on, did not have mercurial installed
(the source had merely been copied over afer cloning). This worked fine.

The machine that was playing up did have mercurial installed, but only
version 1.4, which was exiting with the error "abort: requirement
'dotencode' not supported!"

Either (both were tried and worked) removing mercurial entirely, or
upgrading from 1.4 to 4.0, fixed the build problem
