I suppose this fails because ldc does not recognize 'auto' as a valid option
with flto. It instead needs `full' or `thin'. It also does not seem to recognize
the `-ffat-lto-objects' flag either.
So probably flags should be properly passed and these bug reports should be
either updated or closed for time being. There are a few more ldc-related
bugs (like for mir-core)

Let me know what you'd think?
