This library doesn't really exist any more and is preserved only for
compatibility, there is no need to have dependencies on it, just depend
on "core" instead.
This fixes sporadic errors when building DLL configurations as the html
library build could have been still in progress when xrc library,
requiring it, was linked.
Use the same format as is used by MSVS itself to avoid spurious changes when
modifying the files. Notably:
- Use DOS end of line format (0D 0A).
- Add UTF-8 BOM (EF BB BF) to the beginning of the files.
- Do not put CR LF at the end of the last line in the file.
