RISC-V: For '-march' and '-mabi' options, add 'Negative' property mentions itself.
When use multi-lib riscv-tool-chain. A bug is triggered when there are two
'-march' at command line.

This patch fix it. And the DRIVER would prune the extra '-march' and '-mabi'
options and keep only the last one valid.
gcc/ChangeLog:
* config/riscv/riscv.opt (march=,mabi=): Negative itself.
