Make a ZIP file containing the blob, and catenate it to the end of the executable binary. The ZIP format specifically puts all of the key metadata at the back of the file, so pretty much any ZIP tool can correctly read/list/extract data from the ZIP portion of the file. Anything that needs to be linked at runtime can just be extracted to a temp dir, and then cleaned up on exit. Bonus points for getting "free" compression on text data blobs.

We do this for Python applications, by combining a ZIP containing the "link tree" of sources/packages/modules, with a shell bootstrap script that automatically sets up the environment, import path, etc, and Python itself has built in support for importing pure-python modules from a ZIP file. All that's needed for native modules is a simple import hook that extracts the native objects into temp space and then loads them appropriately.
