Summary: We use a section to embed offloading code into the host for later linking. This is normally unique to the translation unit as it is thrown away during linking. However, if the user performs a relocatable link the sections will be merged and we won't be able to access the files stored inside. This patch changes the section variables to have external linkage and a name defined by the section name, so if two sections are combined during linking we get an error.
