Summary: Add support for LTO
Description:
When compiling both with LTO and debugging symbols enabled (at least in clang)
one must supply the -object_path_lto option:
-object_path_lto filename
When performing Link Time Optimization (LTO) and a temporary mach-o object
file is needed,
if this option is used, the temporary file will be stored at the specified
path and remain after
the link is complete. Without the option, the linker picks a path and
deletes the object file before
the linker tool completes, thus tools such as the debugger or dsymutil will
not be able
to access the DWARF debug info in the temporary object file.
