Last time I needed that, I hacked it up myself; at least back in 32-bit
times, ELF was not that hard (but I had to do that anyway to convert ELF
into something the controller could boot).

Define your memory allocations explicitly. Instead of building a binary
and hacking the strings, place the strings at a fixed address and
regenerate the ELF or .hex file containing them from scratch. Whether
you then give the fixed addresses a name using linker magic, or just
cast pointers, is a matter of taste.
