--- Comment #6 from Georg-Johann Lay ---
As a work around, one can use an adjusted device-specs file with the
avrlibc_devicelib removed. The spec looks like this:
*avrlibc_devicelib:
%{!nodevicelib:-lavr128da32}

This does not work for new devices like AVR128* which also start with mmcu=avr like all cores do. The patch uses a new spec function in order to tell apart cores from devices. gcc/ PR target/107201 * config/avr/avr.h (EXTRA_SPEC_FUNCTIONS): Add no-devlib, avr_no_devlib. * config/avr/driver-avr.cc (avr_no_devlib): New function.

This proposed patch (effectively) sets macro X_NODEVLIB to "" in all of ./config/avr/driver-avr.cc. -nodevicelib is a known driver option from avr.opt, so there should be no need to explicitly remove it by hand by means of %
