Prefer the vs14 targets since we build for Windows
with cl instead of cygwin's gcc. This corresponds
to Visual Studio 2015.
In practice there is little difference, other the
upstream build system assuming a Visual Studio style
output directory, but this should help pick up any
compiler-specific work-arounds.

This is a port of the libvpx scripts, themselves a port of
Chromium's scripts to generate an external build description
using hooks in the upstream configure and make scripts.
The libaom library is a fork of libvpx so we can use a similar
approach.
I've put the upstream source in $(topsrc_dir)/third_party/aom
but the build description and any patches are under the media
directory with the other codecs, similar to how zlib works.
Config files and headers generated by the upstream build system
are also under $(topsrc_dir)/media/libaom/.
