Why are you using using the linker to build your libraries? I build libs
all the time and it only involes compiling and then stuffing the object
files into the lib with avr-ar. After that, building the final app only
uses a single link stage and the single linker script (*.x in all my
projects so far).

Maybe I'm missing something, but I don't understand why (or how) you are
using the linker to build your libraries. The object files are already
relocatable, stuffing them into the lib archive shouldn't change that.
So, it seems to me that you are trying to build a relocatable executable
instead of a library.
