    testsuite: riscv: reset -march for tests with -mcpu
    
    The tests fail when --target_board sets -march to a 32-bit
    architecture.  Override that -march by resetting it, so that the arch
    implied by -mcpu prevails.
    
    
    for  gcc/testsuite/ChangeLog
    
            * gcc.target/riscv/pr114139.c: Reset arch.
            * gcc.target/riscv/pr118170.c: Likewise.
