Fangrui Song 0a46c031d0 riscv: Pass -mno-relax only on lld < 15.0.0 
commit 3cebf80e9a upstream.

lld since llvm:6611d58f5bbc ("[ELF] Relax R_RISCV_ALIGN"), which will be
included in the 15.0.0 release, has implemented some RISC-V linker
relaxation.  -mno-relax is no longer needed in
KBUILD_CFLAGS/KBUILD_AFLAGS to suppress R_RISCV_ALIGN which older lld
can not handle:

    ld.lld: error: capability.c:(.fixup+0x0): relocation R_RISCV_ALIGN
    requires unimplemented linker relaxation; recompile with -mno-relax
    but the .o is already compiled with -mno-relax
