    RISC-V: Update testsuite due to -march string relaxation
    
    We has relaxed -march string, it no longer require canonical order, so
    we need update some of those testcase.
    
    gcc/testsuite/ChangeLog:
    
            * gcc.target/riscv/arch-23.c: Update test.
            * gcc.target/riscv/arch-27.c: Ditto.
            * gcc.target/riscv/arch-28.c: Ditto.
            * gcc.target/riscv/attribute-10.c: Ditto.
