    cat hello.f90 
```
program hello
  ! This is a comment line; it is ignored by the compiler
  print *, 'Hello, World!'
end program hello
```
I try to cross compile hello-world with Flang-new:
```
flang-new  --target=riscv64-unknown-linux-gnu -march=rv64gc --sysroot=/riscv/sysroot --gcc-toolchain=/riscv/ -O3 hello.f90
```

**error: flang-new: error: unknown argument: '--gcc-toolchain=riscv'**


as we know cross compile hello-world with clang:
eg:
clang   --target=riscv64-unknown-linux-gnu -march=rv64gc --sysroot=/home/chunyu/flang/riscv/sysroot --gcc-toolchain=/home/chunyu/flang/riscv/ -O3 hello.c -o a.out 

how to config  --gcc-toolchain for Flang-new
