Summary:                    Linker failure when WINDOWS_EXPORT_ALL_SYMBOLS and
/bigobj are used together in a Win64 build.
Description: 

Shared library fails to link when attempting to use
CMAKE_WINDOWS_EXPORT_ALL_SYMBOLS when compiled with /bigobj.  

Only tested using Visual Studio 14 2015 Win64.

Test project attached.

It appears that printf-family function symbol names are being modified (leading
'_' removed) when cmake is processing *.obj into exportall.def.

Steps to Reproduce: 
Extract attached zip.

> mkdir build
> cd build
> cmake ../ -G "Visual Studio 14 2015 Win64" -DBUILD_BIGOBJ=ON
> cmake --build . --release Debug
