            Bug ID: 193043
           Summary: [CMake][WTF] Finesse i386 architecture detection
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: CMake
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: jmason at ibinx.com

WTF processor architecture is being determined via CMAKE_SYSTEM_PROCESSOR.  On systems which support uname, this is initialized to `uname -p`.

However, the tricky bit is that on some OSes, `uname -p` returns 'i386' for both 32-bit and 64-bit members of the Intel processor family.  Thus, in this case, we must check the pointer size to determine the actual architecture.
