It was a big pain to do the initial steps of the reduction (I had to start with the object files) but, eventually, I managed to do it and from there I reduced it further. Here's a simpler version of the problematic case:

  $ cat test.s
  .global a
  a:
  tail a
  .rept 2008
  .byte 0
  .endr
  
  $ clang --target=riscv64 -c test.s
  $ ld.lld -shared test.o
  ld.lld: error: test.o:(.text+0x0): relocation R_RISCV_RVC_JUMP out of range: 1028 is not in [-1024, 1023]; references a
  >>> defined in test.o
