[PATCH] D129824: [RISCV] Set triple based on -march flag which can be deduced in more generic way

[Fangrui Song via Phabricator via cfe-commits]

MaskRay added a comment.

Both D54214 <https://reviews.llvm.org/D54214> and this look like a surprising behavior to me. Do we still have time to go back the state before D54214 <https://reviews.llvm.org/D54214> and make mismatching --target & -march= an error?

> clang -target=riscv32-- -march=rv64gc

`-target=` => `--target=`
