Issue Description:

As a test, I tried upgrading LLVMSwift's Linux build from the 5.0 release to the 5.1 snapshot. For some odd reason, this caused Swift PM to fail to build our shims package. Attached are the build logs between two different runs of Travis:

  • swift5.txt contains a run with Swift 5.0 in verbose mode

  • swift51.txt contains a run with Swift 5.1 in verbose mode

The Swift 5.1 build indicates an error when trying to access the PC file we write to setup the freshly apt-installed copy of LLVM and Clang as a system library

> 'cllvm' cllvm.pc: �[33m�[1mwarning: �[0minvalidAccess

After that, the command line for clang in the 5.1 log is clearly missing the argument

> -I/usr/lib/llvm-8/include

This used to be inherited from the `cllvm` package, and it still is on macOS.

A branch that reproduces this build failure on Travis' Linux bots is available here: llvm-swift/LLVMSwift#205

Can you provide a smaller reproducer?
