    RISC-V: Fix effective target check.
    
    The return value is inverted in check_effective_target_rvv_zvl256b_ok
    and check_effective_target_rvv_zvl512b_ok.  Fix this and also just use
    the current march.

            * lib/target-supports.exp: Fix effective target check.
    
    (cherry picked from commit e45537f56250f19cdf2ec09a744c6b11170c1001)
