[patch] AVR: Sort .text.* input sections by their name.

[Georg-Johann Lay]

This patch sorts the .text.* input sections by their name
in order to increase code locality, e.g. for code from
libgcc and AVR-LibC.  For example, libgcc puts their
multiplications and helpers in .text.libgcc.mul, but
without SORT the linker may locate functions related by
their input section far apart, inserting function from
unrelated input sections in between them.

Ok for trunk?
