• SR-1567 [SwiftPM] Prevent/solve issue with seeing headers in /usr/include and SDK (was: compiler crash when passing -Xcc -I/usr/include to swiftc)

Issue Description:

I'm having trouble compiling Perfect-CURL submodule of the Perfect web server. I know this Swift board is for Swift issues. But the problem appears to be the Swift compiler and not the Perfect web server codebase.

I have tried to compile this package on 3 macs. The swift compiler crashes on two of them and not on the third one and I don't know why.

Software Specs:
10.11.6
Xcode 8 beta
Swift Snapshot 8-18 toolchain

Step to perform:
git clone https://github.com/PerfectlySoft/Perfect-CURL.git
cd Perfect-CURL
swift build

Mac #​1 (Compiler Crash):
MacBook (Retina, 12-inch, Early 2016)
8GB RAM, 512 SSD

Mac #​2 (Compiler Crash):
MacBook Air (Mid 2009)
2GB RAM, 128GB SSD

Mac #​3 (Build Succeeded):
MacBook Pro (Retina, 15-inch, Mid 2015)
16GB RAM, 512 SSD
