jvmciCompilerToVM.cpp declares jio_printf with "void" return type, should be "int"

Building hotspot with LTO enabled:

$ sh ./configure ... --with-extra-cxxflags="-flto -ffat-lto-objects -fcommon" --with-extra-cflags="-flto -ffat-lto-objects -fcommon"

Yields this warning:

/home/shade/trunks/jdk-jdk/src/hotspot/share/jvmci/jvmciCompilerToVM.cpp:1576:17: warning: 'jio_printf' violates the C++ One Definition Rule [-Wodr]

It seems that only jvmciCompilerToVM.cpp declares the "void" return type.
