Much like GNU debug links, PE/COFF binaries can carry the patch to the binary containing the debugging symbols. Since the kernel binary is loaded by UEFI at an a priori unknown offset in the 1:1 mapping of physical memory, having this information is useful for the debugger automation to find the file and the offset, and load the symbols automatically. So if we have debugging symbols to begin with (CONFIG_DEBUG_INFO=y), add the absolute path to vmlinux to the PE/COFF debug table.
