For later versions of MacOS, the dynamic loader is more picky about enforcing restrictions on __DWARF MachO load commands/segments, triggering aborts of the form dyld: malformed mach-o image: segment __DWARF has vmsize < filesize for Go programs that use cgo on Darwin. The error is being triggered because the Go linker is setting "vmsize" in the DWARF segment entry to zero as a way to signal that the DWARF doesn't need to be mapped into memory at runtime (which we need to continue to do). This patch changes the initial protection on the __DWARF segment to zero, which dyld seems to be happy with (this is used for other similar non-loadable sections such as __LLVM).
