Error in backend: invalid llvm.linker.options building SourceKit-LSP on Ubuntu 18.10


I am following this tutorial in order to get Visual Studio Code and SourceKit-LSP integrated on Ubuntu 18.10, however, I got stuck at building sourcekit-lsp project.

The error I'm getting:

fatal error
: 
error in backend: invalid llvm.linker.options


clang: error: clang frontend command failed with exit code 70 (use -v to see invocation)
clang version 7.0.0-3 (tags/RELEASE_700/final)

Thread model: posix
InstalledDir: /usr/bin
clang: note: diagnostic msg: PLEASE submit a bug report to https://bugs.llvm.org/ and include the crash backtrace, preprocessed source, and associated run script.

I'm not sure if its relevant, but after typing Swift in the console I get the following errors:

Welcome to Swift version 5.0-dev (LLVM b10ce3d642, Clang c1979d7668, Swift 94b167db75).
Type :help for assistance.

I would appreciate if anyone could give me a hint how to solve the problem. The only thing that came up to my mind was reinstalling clang, but it hasn't solved the issue.
