Compile bug: RISCV cross-compile warnings cause build failure #12693

Problem description & steps to reproduce
I am updating the CI with cross-compile builds for RISCV regression tests (see #12428 ) and a build error is occurring due to some RISCV macros/functions. Since I am not familiar with RISCV functions in question, I am deferring this fix to folks who know that platform better.
