Technical tradeoffs

• Hardcoding `-march=rv32i` makes the testcase less flexible but more robust against build configuration variations.
• Ensuring test isolation from build-time architecture flags improves test reliability.

[PATCH] RISC-V: Fix fmv.x testcase for non-default --with-arch

This patch addresses a failing test case in the gas testsuite for RISC-V. The fmv.x testcase was not passing the -march flag, leading it to inherit the default architecture configured at build time. This caused failures when build configurations used non-default --with-arch options, such as rv32e* or rv32i_zfinx. The fix ensures the test explicitly uses -march=rv32i which is sufficient for its purpose of verifying fmv.x.s/fmv.s.x as aliases of fmv.x.w/fmv.w.x.
