Yes. If we release from revision r2473 it will work with gcc-5.1, not

If we release from last revision r2474, it will work with gcc trunk, not

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+
