[PATCH] D29817: [AVR} Fix __AVR_xxx macro definitions

[Peter Wu via Phabricator via cfe-commits]

Lekensteyn created this revision.

The -mmcu option for GCC sets macros like __AVR_ATmega328P__ (with the trailing
underscores), be sure to include these underscores for Clangs -mcpu option.

See "AVR Built-in Macros" in https://gcc.gnu.org/onlinedocs/gcc/AVR-Options.html
