Package request: libc-avr and avr-gcc

A toolchain for working with atmel microcontrollers, particularly compiling asm and C code. http://www.nongnu.org/avr-libc/ I haven't tried to build the packages myself yet, since compiling in termux is somewhat different from usual compiling and installing. Since there are already numerous android apps for flashing atmel microcontrollers, it might come in handy to be able to compile the firmware right on the android device.
