[Suggestion] are they toolchains' issue?

Hello Maintainers:

When compiling with allmodconfig for v4, an error occurs:

    CC      kernel/fork.o
  /tmp/ccTx69dj.s: Assembler messages:
  /tmp/ccTx69dj.s:7853: Error: invalid instruction `if (tstbit(r4.new,r0))jump:nt .L242'

Also when with allmodconfig (default for v2), it will cause error:

  /usr/local/bin/hexagon-ld: Relocatable linking with relocations from format elf32-littlehexagon (init/.tmp_main.o) to format elf32-littlehexagon (init/main.o) is not supported

Also when with defconfig, it will cause error:

    LD      init/mounts.o
  /usr/local/bin/hexagon-ld: Relocatable linking with relocations from format elf32-littlehexagon (init/do_mounts.o) to format elf32-littlehexagon (init/mounts.o) is not supported
