    AVR: target/107201: Make -nodevicelib work for all devices.

            driver-avr.cc contains a spec that discriminates between cores
            and devices by means of a mmcu=3Davr* spec pattern.  This does =
not
            work for new devices like AVR128* which also start with mmcu=3D=
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.
            (avr_devicespecs_file): Use it to remove -nodevicelib from the
            options for cores only.
            * config/avr/avr-arch.h (avr_get_parch): New prototype.
            * config/avr/avr-devices.cc (avr_get_parch): New function.
