Old version of compiler

[Andres G. Aragoneses]

F# compiler in ubuntu is really old. This is taken from Focasa preview:

$ fsharpc --help
F# Compiler for F# 4.0 (Open Source Edition)
Freely distributed under the Apache 2.0 Open Source License

$ dpkg --list | grep fsharp
ii fsharp 4.0.0.4+dfsg2-2

This compiler has bugs that upstream new versions of F# don't have, for example:

a) Create a file "bug.fs" with this content:

```
let FindInFile (someStrings: seq<string>) =
    for line in System.IO.File.ReadLines "someFile" do
        for someString in someStrings do
            System.Console.Write line

FindInFile ["x";"y"]
```

Compile it with `fsharpc bug.fs`

Current results:
F# Compiler for F# 4.0 (Open Source Edition)
Freely distributed under the Apache 2.0 Open Source License

/home/knocte/Documents/geewallet/bug.fs(4,34): error FS0971: Undefined value 'line : string'

Expected results (what happens with newer F# in Windows):
C:\Users\knocte>"C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\Common7\IDE\CommonExtensions\Microsoft\FSharp\fsc.exe" bug.fs
Microsoft (R) F# Compiler version 10.8.0.0 for F# 4.7
Copyright (c) Microsoft Corporation. All Rights Reserved.

C:\Users\knocte>

(no error)

b) The bundled version of the tool "fsharpi" is also buggy, see https://github.com/fsharp/fsharp/issues/740
