Distros other than Vanilla Ubuntu have some issues #118
Description
I'm on Elementary OS, an Ubuntu-based Linux. The Swift binaries compiled for Ubuntu 16.04 are fully compatible with it. But if using swiftenv, I get two results depending on how I install Swift:
swiftenv install N:
It first downloads the repos:
- swift
- swift-llvm
- swift-clang
- swift-lldb
- swift-cmark
- swift-llbuild
- swift-package-manager
- swift-compiler-rt
- swift-corelibs-xctest
- swift-corelibs-foundation
- swift-corelibs-dispatch
Then proceeds to compile Swift:
Building Swift
This may take a very long time...And after that when I run swift (to invoke the REPL), I get this error:
<unknown>:0: error: unable to load standard library for target 'x86_64-unknown-linux-gnu'

After this happened, I decided to try again with a directed binary installation:
swiftenv install https://swift.org/builds/swift-4.1-release/ubuntu1604/swift-4.1-RELEASE/swift-4.1-RELEASE-ubuntu16.04.tar.gz

Welcome to Swift version 4.1 (swift-4.1-RELEASE). Type :help for assistance.
1> Which works no problem 👍
What can be done
I think the best alternative is to build under non-ubuntu-based distros and figure out what's wrong with the build process that doesn't let it build or configure properly the Stdlib, s.t. they can actually use swiftenv.
And under ubuntu-based distros, having a way to tell what ubuntu are they based on. Then, proceeding to just install the binaries as if they were that particular ubuntu.
What I don't know
Does building work properly under vanilla Ubuntu? Maybe the stdlib gets properly built or configured iff that's the OS swiftenv is under.
Extras
I tested this both under Swift 4.0 and 4.1, to make sure it wasn't my 4.1 PR that made swiftenv fail.
