This is unrelated but I recommend not using “sudo” here.  You can add a
udev rule to your system configuration to change the ownership of
/dev/ttyACM0.

For my AVR programmers I have this in my system configuration:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
(define avrispmkii-udev-rule
  (udev-rule "90-avrispmkii.rules"
             "\
SUBSYSTEM!=\"usb\", ACTION!=\"add\", GOTO=\"avrisp_end\"

# Atmel Corp. JTAG ICE mkII
ATTR{idVendor}==\"03eb\", ATTR{idProduct}==\"2103\", MODE=\"660\", GROUP=\"dialout\"
# Atmel Corp. AVRISP mkII
ATTR{idVendor}==\"03eb\", ATTR{idProduct}==\"2104\", MODE=\"660\", GROUP=\"dialout\"
# Atmel Corp. Dragon
ATTR{idVendor}==\"03eb\", ATTR{idProduct}==\"2107\", MODE=\"660\", GROUP=\"dialout\"

LABEL=\"avrisp_end\"\n"))

(operating-system
  …
  (services (cons* (modify-services %desktop-services
                     (udev-service-type config =>
                                        (udev-configuration
                                         (inherit config)
                                         (rules (append (udev-configuration-rules config)
                                                        (list avrispmkii-udev-rule))))))))

This is a bug in our AVR toolchain.  The internal search path for these
files appears to be wrong.  What I did was copy the “crt*.o” file I
needed to my working directory.  Maybe you can send an email to
bug-guix@gnu.org to report this as a bug?

You only need “avr-toolchain” as it contains all the other packages.
