We have scripts (written in python) that are run after a binary image is
created in the tools. These scripts are not really exportable, as they
are part of the tools and may include and use any bits of python code
they please. So we don't export them. This patch disables export
combinations that would not work because the post-binary hook is not
exported. A white-list is used for forward compatibility.
* Rename because the tool has been renamed
* Removed duplicate symbol definitions
* Removed common flags from ld flags (common are c/c++ only)
* Moved EmBlitz to it's own folder
