From version 2.35, binutils can be configured with
--enable-mips-fix-loongson3-llsc=yes, which means it defaults to -mfix-loongson3-llsc. This breaks labels which might then point at the wrong instruction.
The workaround to explicitly pass -mno-fix-loongson3-llsc has been added in Linux version 5.1, but is only enabled when building a Loongson 64 kernel. As vendors might use a common toolchain for building Loongson and non-Loongson kernels, just move that workaround to arch/mips/Makefile. At the same time update the comments to reflect the current status.

I've applied it to mips-next, but I consider such changes as rather rude. I would have expected, that the workaround is only enabled via command line option and not by default.
