Description
I am still working through this problem. I have a project for an ATmeg64m1 that was compiling using a make file with avr-gcc 4.9.1. After the update to 7.1.0 it fails because it cannot find the request crt file.
I know it is locating the spec file because the messages in the log show the path for the library is "avr5":

The line:
/opt/local/lib/gcc/avr/7.1.0/../../../../avr/bin/ld: cannot find crtatmega64m1.o: No such file or directory
Indicates the linker cannot find the particular start file for my device.
Then I look in the spec file "specs-atmega64m1", I see
. . . *avrlibc_startfile: crtatmega16m1.o%s. . .
But the files are named: Proton:avr5 wayne$ ls -al *m1.o -rw-r--r-- 1 wayne wheel 10688 Jul 24 10:34 atmega32m1.o -rw-r--r-- 1 root wheel 10688 Jul 24 10:34 crtm16m1.o -rw-r--r-- 1 root wheel 10688 Jul 24 10:34 crtm32m1.o -rw-r--r-- 1 root wheel 10688 Jul 24 10:34 crtm64m1.o Proton:avr5 wayne$ pwd /opt/local/avr/lib/avr5
if I rename the file "crt64m1.o" to "crtatmega64m1.o" then I get a little further but there is still a problem:

This is because the same spec file indicates:
. . . *avrlibc_devicelib: %{!nodevicelib:-latmega64m1} . . .
when I search on my machine for any file with this name I cannot find the file.
Proton:avr5 wayne$ sudo find /opt -name "*64m1*" /opt/local/avr/include/avr/iom64m1.h /opt/local/avr/lib/avr5/crtatmega64m1.o /opt/local/avr/lib/avr5/crtm64m1.o /opt/local/lib/gcc/avr/7.1.0/device-specs/specs-atmega64m1
note: The file "/opt/local/avr/lib/avr5/crtatmega64m1.o" is a copy of "/opt/local/avr/lib/avr5/crtm64m1.o" which I renamed.
So right now I am stuck because I do not know where to find this file or what it should be changed to (if appropriate).
