    RISC-V: testsuite: Do not set default arch for RVV.
    
    This removes setting of the default arch and abi in the testsuite.  We
    should directly use what the target provides.
    
    gcc/testsuite/ChangeLog:
    
            * gcc.target/riscv/rvv/rvv.exp:  Remove -march and -mabi from
            default CFLAGS.
