Isn't c4x only about 2 years old?  I haven't used it yet, but a free
software compiler for popular DSP chips would be a very good thing
indeed.   That would cover the dsp16xx as well.

It doesn't seem so strange that they don't support ELF, given that a
DSP application is often just a single chunk of code that completely
owns the machine, no traces of an OS anywhere.
