Added ARCHITECTURE to ALTERNATE_CORE_PATH to support 1.5+ cores like arduino-tiny.

sej7278 · sej7278 · commit 356f5b3e04d4 · 2015-03-25T19:29:21.000Z
arduino-tiny and damellis' attiny85 cores don't use a vendor, but they
do use the avr architecture (subdirectory) in their 1.5/1.6 branches.

arduino-tiny builds and is auto-detected now, still needs some
work to support sub-cpu's and clocks.

damellis doesn't compile, but that's not our makefile it seems.
