  -----------
  Use gcc-9 in the Scout runtime instead of gcc-5.

The gcc-9 shipped with the Scout runtime forces the use of -static-libstdc++ which is what allows this to work. However, LTO is not yet able to be enabled since as of right now it simply crashes immediately with `free(): invalid pointer`.
