R_MIPS_PC32 exists as a GNU extension.
R_MIPS_PC64 existed, but was removed by https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=4030e8f62467c29b782aa2480e1e452b8e458699
(like all the old commits, the description just recorded what the commit *did*. There was no *why*.)

This just makes certain things unnecessarily complex.

* DW_EH_PE_pcrel|DW_EH_PE_sdata8 => ?
* __patchable_function_entries has to have the SHF_WRITE flag on MIPS https://gcc.gnu.org/ml/gcc/2020-01/msg00106.html
   .quad foo - . => Error: PC-relative reference to a different section
