Khem Raj bb73f2f789 riscv: Use -mno-relax when using lld linker
[ Upstream commit ec3a5cb61146c91f0f7dcec8b7e7157a4879a9ee ]

lld does not implement the RISCV relaxation optimizations like GNU ld
therefore disable it when building with lld, Also pass it to
assembler when using external GNU assembler ( LLVM_IAS != 1 ), this
ensures that relevant assembler option is also enabled along. if these
options are not used then we see following relocations in objects

0000000000000000 R_RISCV_ALIGN     *ABS*+0x0000000000000002

These are then rejected by lld
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
