Manifest-related problems with b2 building in msvc-14.0

[joaquintides]

Starting with B2 5.0.0, building b2 with msvc-14.0 (toolset vc14) fails with:

LINK : fatal error LNK1158: cannot run 'mt.exe'

Full log here. Seemingly this is related to manifest embedding, as defining B2_DONT_EMBED_MANIFEST when building b2 solves the problem. Ideally, this shouldn't be necessary as it wasn't pre 5.0.0.

Thank you!

I'm starting to suspect this is a consequence of a badly configured msvc install. As it works with the same toolset in Appveyor.. https://ci.appveyor.com/project/bfgroup/b2/build/job/f5fqmt4vvg6i7kiv -- And since it's msvc itself that is invoking mt.exe, and not finding it, increases my suspicion to that conclusion. I.e. msvc itself thinks mt.exe should be there.

That error usually means Windows SDK is missing.
