[swift-dev] Build failure on s390x

After apply this commit, the s390x build started to fail:

The commit added 2 new functions in
stdlib/public/SwiftShims/RuntimeStubs.h.  They are used in
stdlib/public/stubs/CommandLine.cpp with SWIFT_CC(swift) macro.  Since we
use the LLVM's intrinsic "swiftcall" on s390x, this caused a build error.
To fix it we added the SWIFT_CC(swift) macro and #include
"swift/Runtime/Config.h" to RuntimeStubs.h.  We then ran into this build

<module-includes>:9:10: note: in file included from <module-includes>:9:
#include "RuntimeStubs.h"
'swift/Runtime/Config.h' file not found
#include "swift/Runtime/Config.h"

I tried modifying stdlib/public/SwiftShims/CMakeLists.txt with


But that didn't seem to work.  Any suggestions on how to fix this?

Thanks for your help!
