Add (hopefully last) remaining missing dependences to llvm-lto2

There are still a few missing symbols reported by:
http://bb.pgr.jp/builders/i686-mingw32-RA-on-linux/builds/15535/steps/build_llvmclang/logs/stdio
http://bb.pgr.jp/builders/i686-mingw32-RA-on-linux/builds/15535/steps/build_llvmclang/logs/stdio

This should hopefully take care of them.
