[ Upstream commit 3c1918c8f54166598195d938564072664a8275b1 ]
When building with the LLVM linker this error occurrs: LD arch/riscv/kernel/vdso/vdso-syms.o ld.lld: error: no input files
This happens because the lld treats -R as an alias to -rpath, as opposed to ld where -R means --just-symbols.
Use the long option name for compatibility between the two.
