Issue Description:

After downloading Swift 4.2 on Ubuntu 18.04 and installing clang there is this error when trying to compile even the simplest program:

/usr/bin/ld: cannot find -lstdc++

Here is the full text of the error (when calling swift build):

Linking ./.build/x86_64-unknown-linux/debug/MonTest /usr/bin/ld.gold : erreur : -lstdc++ introuvable clang: error: linker command failed with exit code 1 (use -v to see invocation) <unknown>:0: error: link command failed with exit code 1 (use -v to see invocation) error: terminated(1): /home/username/Bureau/swift-4.2-release/usr/bin/swift-build-tool -f /home/username/MonTest/.build/debug.yaml main output:

And the same error with the -v option :

Even when installing all possible recommended dependencies for Swift the problem isn't solved.

@shahmishal, have we seen this before?

@belkadanI have not seen this issue before, adtrevor (JIRA User) I am going to try to reproduce this issue on new Ubuntu 18.04 system. Can you provide the steps you took to install Swift and other packages?

@shahmishal Thank you for your reply, the issue I have is that this isn't a clean Ubuntu install, so there are already installed packages that might be interfering.

I followed the installation steps described on swift.org, installed the latest clang version and also ran `sudo apt-get -y install libicu-dev libpython2.7 libcurl4` as this was required to make it work on clean Google Cloud instance I used, but unfortunately this didn't solve it on this machine.

About the required dependencies on Ubuntu 18.04, I did a new install and it seems that all I needed to install on a clean Google instance was clang and libpython2.7, it would be great if the install instructions were updated to match those.

About the problematic machine, I have to say that I don't understand at all what concretely causes this issue since all dependencies should be installed.
