5692ed0cce8c95, but with the ORC runtime disabled explicitly on
CrossWinToARMLinux to match the other compiler-rt runtime libraries.
Differential Revision: https://reviews.llvm.org/D112229
---
Enable building the ORC runtime for 64-bit and 32-bit ARM architectures,
and for all Darwin embedded platforms (iOS, tvOS, and watchOS). This
covers building the cross-platform code, but does not add TLV runtime
support for the new architectures, which can be added independently.
Incidentally, stop building the Mach-O TLS support file unnecessarily on
other platforms.
