The stage3b loader memory layout must not be larger than 0x10000 bytes.
Let's check this in the linker script.

+ the input section names `.text.init` and `.text.start` aren't
ambiguous, therefore there is no reason so specify a file name
+ discard `.interp` section since no loader is used

Normally, `gcc` takes care of adding the `GNU_STACK` marking except for
assembly code. Therefore, let's add the marking manually. Discard the
`.note.GNU-stack` section in the linker script since it's just a
"message" from the compiler to the linker. This fixes the linker
warning:
ld: warning: entry.o: missing .note.GNU-stack section implies executable stack

Use C pre-processor for linker script generation. This allows the
usage of constants in our "linker scripts" `*.lds.S` (actually, these
are assembler files, so we can make us of the C pre-processor and its
capabilities).
