Vorbis lib folder naming convention in source

While trying to solve an html export error, I found out that VorbisLibPath for HTML has a naming problem.

On OSX the files that are looked for linking are located under …/lib/HTML5/(libvorbisxxx.bc) when the launcher build (4.9) is installed.
However, in the source the folder is called as Lib, and is compiled as is.

This will create a file not found error in python while emscripten is crunching numbers, for case sensitive journaled file systems.
Also can be a problem for Android builds.

Here is a link to the class:
