Debugging with LTO in GCC 7 doesn't work well.

See https://gcc.gnu.org/gcc-8/changes.html#general

* Link-time optimization improvements:

   We have significantly improved debug information on ELF targets
   using DWARF by properly preserving language-specific information.
   This allows for example the libstdc++ pretty-printers to work with
   LTO optimized executables.
