There are no elegant solutions because there has been no real need.

Today the biggest drivers are:

* CPU / FPGA combinations.

* CPU / GPU combinations.

They are all usually proprietary and use a single ELF binary with embedded
data in specially named sections.

The notion of a multi-arch ELF binary doesn't exist, and relocation
numbers overlap between architectures, so you would really really need
to find a way to isolate the architecture components.

Your only option is probably FatELF [1], and it would be nice if we saw
more universal acceptance of something like that.
