[Boost-build] embed manifest file

Hello,

i want to embed a user-defined manifest in the build dll.
i tried to extend the msvc-linking-generator and it seems now it 
correctly builds and embeds a user supplied manifest file.
Can someone comment on the attached patch?
I extended the msvc-linking-generator to create an extra target for 
embedding the manifest file. The extra target (MANIFESTLOG) is a dummy 
file as embedding the manifest file only modifies the dll without 
creating a new file.
Is this the correct way?

Best regards,

Bernhard
