Enable libstdc++ compilation on AVR targets
Enable libstdc++ compilation in AVR targets with AVR-Libc. Most
floating point math functions are already defined in AVR-Libc, so
defines are in place to avoid multiple definition of these functions.
2016-12-06 Felipe Magno de Almeida <felipe@expertisesolutions.com.br>
* crossconfig.m4: Add avr target for cross-compilation.
* configure: Regenerate.
