For non fat ("slim") LTO builds you need to use these tools yes. ar needs to
know the symbol table for its index and that needs LTO specific knowledge.
This follows other slim lto compilers like LLVM or icc.
There's no special documentation because the usage is the same as the standard
ar/ranlib/nm. The lto documentation hints at them, but could be perhaps
clearer.
