MSVC 2010+ Builds: Fix .pdb Generation

MSVC 2010+ Builds: Fix .pdb Generation

For Visual Studio 2010 and later, the .pdb filename needs to be explicitly
specified so that it will match the filename of the target, if the project
name differs from the filename of the target.  Make sure that is the case
for the 3 DLLs that we build for Visual Studio 2010 and later.
