Yes. If we release from revision r2473 it will work with gcc-5.1, not
trunk.
If we release from last revision r2474, it will work with gcc trunk, not
gcc-5.1.
It will also work with 5.1.1 and up.
Following table illustrates the crt file and device library name/layout
expected by gcc. AVR-LibC configure is updated to follow this layout.
Example: atmega1280
+----------------+-------------+-------------------------+-----------------+
| | GCC < 5.0.0 | GCC 5.1.0 | Others |
+----------------+-------------+-------------------------+-----------------+
| crt file | crtm1280.o | crtm1280.o | crtatmega1280.o |
+----------------+-------------+-------------------------+-----------------+
| device library | | dev/atmega1280/libdev.a | libatmega1280.a |
+----------------+-------------+-------------------------+-----------------+
avr-gcc 5.1.0 will use dev/atmega1280/crt1.o%s as start file where %s means to
search in multilib paths.
For the change see https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65296#c10
which is also a backport to 5.1.1+
