When building zig test cases for `hexagon` with `lld`, we encounter range limitations in the relocations, see below for errors. The limited range of these relocations is expected behavior, but for users making large programs it's undesirable. `lld` can make extensions using thunks/trampolines, but those aren't yet supported.
Note also that #116798 improved `lld` by correcting the range calculation - it was previously too small. But that fix alone is not effective for very large programs.
Thanks @alexrp for the bug report.
