added a half-working MakeFile for linux to Session1/Task1. More to come

Session1/Task1/Makefile

+#	This is a Makefile for AVR KURS,
+#	attempting to provide support for compiling and flashing from Linux
+
+# CHANGE THIS TO THE FOLDER YOU PUT YOUR DOWNLOADS IN
+#  The avr_toolchain and DFP folders should be put in the following defined folder
+DOWNLOAD_DIR=/home/magne/avr/
+
+# WHERE GET THIS? 
+#  This toolchain package can be downloaded from Atmel:
+#  http://www.atmel.com/tools/ATMELAVRTOOLCHAINFORLINUX.aspx
+#  
+AVR8_TOOLS_DIR=$(DOWNLOAD_DIR)atmel_avr_toolchain/
+
+# WHERE GET THIS?
+#  This DPF folder can be found in the 
+#  Atmel ATtiny Series Device Support (1.2.112)
+#  AtPack downloaded from:
+#  http://packs.download.atmel.com/
+#
+#  However, the AtPack must be unpacked by Atmel Studio (read: Windows.exe),
+#  so it is best transferred from a friend. [ INCLUDE A DOWNLOAD ON THE COURSE PAGE? ]
+#  In this case, the Attiny folder should be located somewhere like this:
+#  "C:\Program Files (x86)\Atmel\Studio\7.0\packs\atmel\Attiny_DFP\1.2.112" ...
+#  ... after being unpacked by Atmel Studio.
+#
+DFP_DIR=$(DOWNLOAD_DIR)dfp/1.2.112/
+
+# The important options for avr-gcc are
+# -B directory for spec-file folder from DFP pcakage
+# -I directory for includes from DFP package
+# -mmcu device id
+# -o output file [in HEX ??]
+compile:
+	$(AVR8_TOOLS_DIR)bin/avr-gcc -B $(DFP_DIR)gcc/dev/attiny817 -I $(DFP_DIR)include -mmcu=attiny817 -Os -o task1.hex main.c
+
+# and here make some rules for flashing through pyupdi
