[swift-dev] Swift CI PR builder dispatch linux failure

The order may need to vary by platform.  On Linux, the DIspatch Swift
overlay code lives in swift-corelibs-libdispatch/src/swift.  So it works to
build (1) Swift (2) libdispatch (both C and Swift) (3) Foundation.

I think the right order to build things is:

1. libdispatch (C)
2. Swift (compiler + stdlib + Dispatch overlay)
3. Foundation

Otherwise we need to build Swift, then build libdispatch, then go back to
"Swift" to build the overlay, and only finally get to Foundation.

      I don’t know how these dependencies are expressed in CMake but it
      doesn’t seem very difficult to do so in the autotools buildsystem, we
      have

      AC_ARG_WITH([swift-toolchain],
      [AS_HELP_STRING([--with-swift-toolchain], [Specify path to Swift
      toolchain])],
      [swift_toolchain_path=${withval}
      AC_DEFINE(HAVE_SWIFT, 1, [Define if building for Swift])
      SWIFTC="$swift_toolchain_path/bin/swiftc”

      in configure.ac which ends up as a SWIFTC makefile variable, so as
      long as that argument is passed as an absolute path, it should work
      as a dependency in the build rules

      $(abs_builddir)/swift/%.o: $(abs_srcdir)/swift/%.swift
      $(SWIFTC) -frontend -c $(SWIFT_ABS_SRC_FILES) -primary-file $< \

      Is there a JIRA ticket for this ? the IBM folks should probably be
      the ones making these changes since we still don’t have the whitelist
      in place for Apple contributors to do so…

                  Daniel: how hard would it be for the Dispatch project to
                  be modified to add the swiftc binary used to build the
                  project as a dependency?
