CMake doesn't handle linker export files in a general way well. On
Windows it is able to recognize a .def file and pass it to the linker.
Unfortunately it cannot do the same thing on Linux, so we have to
manually specify it.
Note that CMake can't recognize the current Windows export file due to
the .in suffix, hence why the amdhip.def file is being added. The
hip_hcc.def.in file will be removed later, as the Makefile build still
uses it.
