           Product: flang
           Version: trunk
          Hardware: PC
                OS: Linux

Please add --version option to flang. Currently it just hangs waiting for stdin

This breaks configure scripts that run compilers with --version option [all
currently known compilers either provide the version info - or giver error
message - not hang]

[balay at pj01 ~]$ clang --version
clang version 11.0.0 (https://github.com/llvm/llvm-project.git
5c3ebd77259d8438663a3abe334a80a7ddf5caef)
Target: x86_64-unknown-linux-gnu
Thread model: posix
InstalledDir: /home/balay/soft/llvm-dev/bin
[balay at pj01 ~]$ flang --version
<hang>
