<pre>When using gcc 4.9, I got the following errors.
This is because for gcc 4.9 When using a linker plugin, compiling with the
-flto option now generates slim objects files (.o) which only contain
intermediate language representation for LTO. Use -ffat-lto-objects to create
files which contain additionally the object code.
So a quick fix is to add '-ffat-lto-objects' when -flto is used.
