[patch, avr, applied] Use libiberty's XALLOCAVEC instead of alloca

[Georg-Johann Lay]

This is a no-op change that uses libiberty's XALLOCAVEC instead
of alloca.  Applied to trunk as obvious.

AVR: Use libiberty's XALLOCAVEC instead of alloca.

gcc/
        * config/avr/avr.cc (avr_init_builtins): Use XALLOCAVEC
        instead of alloca to locally alloc char[].
        * config/avr/avr-c.cc (avr_cpu_cpp_builtins): Same.
        * config/avr/avr-log.cc (avr_log_set_avr_log): Same.
