gnu: make-avr-toolchain: Add a #:xgcc argument.
This allows generating an AVR toolchain for any version of GCC. * gnu/packages/avr.scm (make-avr-gcc): Add a #:xgcc argument; use memoize instead of mlambda. (make-avr-libc): Likewise. Provide it to the 'make-avr-gcc' call. (make-avr-toolchain): Add a #:xgcc argument; use memoize instead of mlambda. Provide the xgcc argument to the 'make-avr-libc' and 'make-avr-gcc' procedures.
