The symbol version for _mcount was removed 12 years ago in r169525 from gmon/Symbol.map, to be added to the per-arch Symbol.map. mips was overlooked in this, so _mcount has no symver. Add it back to where it should have been, rather than where it would go if it were added today, since we're correcting a historical mistake. Additionally, _mcount is getting thrown into .mdebug.abi32 in the llvm80/90 world as it's not getting explicitly thrown into .text, so do this now. This fixes the libc build that was previously failing due to relocations in .mdebug.abi32. This is specifically due to the way clang's integrated AS works and that they emit the .mdebug.abiNN section early in the process. An LLVM bug has been submitted[0] and an agreement has been made that the mips backend should switch to .text following .mdebug.abiNN for compatibility.
