[swift-users] Build doesn't find ioctl.h

[Lane Schwartz]

Thanks. I'd like to test this fix on Scientific Linux 7.1, but I'm having
trouble applying the patch. I replaced stdlib/public/Glibc/CMakeLists.txt
with the version from this commit, and likewise removed
stdlib/public/Glibc/module.map and added the stdlib/public/Glibc/
module.map.in from this commit.

But after doing so, the build doesn't know how to create
stdlib/public/Glibc/module.map:

   - /home/lanes/cmake-3.4.1-Linux-x86_64.binary_distribution/bin/cmake
   --build /home/lanes/swift/build/Ninja-DebugAssert/swift-linux-x86_64 -- all
   swift-stdlib-linux-x86_64 ninja: error:
   '/home/lanes/swift/swift/stdlib/public/Glibc/module.map', needed by
   'lib/swift/glibc', missing and no known rule to make it

How should this fix be applied? Sorry for such a simple question - I'm
fairly new to cmake and don't know ninja at all.
