[patch] AVR: Sort .text.* input sections by their name.
This patch modifies the AVR linker script to sort .text.* input sections by their name. The goal is to increase code locality, specifically to prevent functions from libgcc and AVR-LibC that are related and residing in separate .text.* sections from being placed far apart in the final executable. This ordering aims to improve performance by keeping related code closer together.
