Pull RISC-V fixes from Paul Walmsley:

 - fix broken clang build on versions earlier than 19 and binutils
   versions earlier than 2.38.

   (This exposed that we're not properly testing earlier toolchain
   versions in our linux-next builds and PR submissions. This was fixed
   for this PR, and is being addressed more generally for -next builds.)

 - remove some redundant Makefile code

 - avoid building Canaan Kendryte K210-specific code on targets that
   don't build for the K210
