We create an object file in assembly which introduces the symbol `__node_text_start` into the .text section and place the resulting object file as the first file the linker encounters. We do this to ensure that we can recognize the boundaries of the .text section when attempting to establish the address range to map to large pages. Additionally, we rename the section containing the remapping code from `.lpstub` to `lpstub` so as to take advantage of the linker's feature whereby it inserts the symbol `__start_lpstub` when the section's name can be rendered as a valid C variable. We need this symbol in order to avoid self-mapping the remapping code to large pages, because doing so would cause the process to crash.
