It was a strange: xgcc (new) was called with '-mmcu=avr35'
options: but the error message was not about this unsupported
architecture. It was about: line XXX at .../libgcc.S: illegal
opcode movw. Simple 'avr-as -mmcu=avr35' gives normal error
message: Fatal error, unknown MCU, avr35.
About the question: probably, it is possible by setting
variable MULTILIB_EXCEPTIONS.
