The linker in the LLVM project is called "lld". It's pretty good for
ELF, but you'll have to implement the parts for your target
(specifically exactly how R_XXX_MOVI does its job in this case).
Alternatively, if your platform already has GCC support you can use ld
from GNU binutils, but you'll probably have to cross-compile it
yourself.

Cheers.
