+	  Generate debug info into separate .dwo files. This significantly
+	  reduces the build directory size for builds with DEBUG_INFO,
+	  because it stores the information only once on disk in .dwo
+	  files instead of multiple times in object files and executables.
+	  In addition the debug information is also compressed.

+	  Requires recent gcc (4.7+) and recent gdb/binutils.
