  In general gcc toolchain folder contains several targets, for instance,
  baremetal and Linux ones. The precommitted tests address this case by
  adding `riscv64-unknown-linux-gnu/` to toolchain folder. This breaks driver's
  include and lib paths, since riscv baremetal triple is now normalized to
  "riscv{32|64}-unknown-unknown-elf" rather than just to "riscv{32|64}-unknown-elf",
  and `GCCInstallation` uses this search priority: "riscv{32|64}-unknown-linux-gnu",
  "riscv{32|64}-linux-gnu", "riscv{32|64}-unknown-elf", choosing Linux target.
  This patch fixes this issue by passing triple alias for baremetal target.
