This patch set adding basic -march option support and feature test marco for
vector extensions, and also extend the syntax of arch string for vector
extensions, although that should change RISC-V ISA manual first would be
better, but we don't got response[1] yet, and that will block whole vector
extensions, so we decide fix that first.
