Allow building with clang

+ Release mode is sort of broken, as lto doesn't work with linker
  relaxation and turning the relaxation off causes issues with the jump
  from init to kernel (as I've currently implemented it, could probably
  be fixed with a manual jump from assembly, I'll add it to my TODO
  list)
