avr-libc: add support for avr-libc C library This commit adds support for the avr-libc C library. According to the project page at http://www.nongnu.org/avr-libc , the avr-libc package provides a subset of the standard C library for Atmel AVR 8-bit RISC microcontrollers. In addition, the library provides the basic startup code needed by most applications. Support for this library in crosstool-ng is only enabled for the AVR 8-bit target. The avr-libc manual and most distributions build the AVR 8-bit gcc toolchain with the "avr" (non-canonical) target. Some experimentation also led to the conclusion that other (canonical) targets are not very well supported, so we force the "avr" target for crosstool-ng as well. The manual also recommends building avr-libc after the final gcc build. To accomplish this with crosstool-ng, a new do_libc_post_cc step is added, in which currently only avr-libc performs its build, and is a no-op for the other libc options.
