Updated BUILD.txt for Linux 

Updated with Linux information tested on Ubuntu.

Had to install sam-1.6.6 myself, download from ttp://downloads.arduino.cc/cores/sam-1.6.6.tar.bz2 and extract to arduino-1.6.7/hardware/arduino/
Modify platform.txt as with Windows/OSX, but path changes slightly from ARM to GCC: "{build.system.path}/CMSIS/CMSIS/Lib/GCC/libarm_cortexM3l_math.a"

2. You'll need to open the file in a text editor and find the line:
On Linux, it's located in my home directory, downloaded and extracted from Arduino website, but must be installed.
/home/m1geo/arduino-1.6.7/hardware/arduino/sam
I (M1GEO) found it was necessary to download SAM-1.6.6 outside of the Arduino IDE, and manually extract the files.
The Board Manager didn't seem to install the SAM files correctly. Here's how I did it:
a) wget http://downloads.arduino.cc/cores/sam-1.6.6.tar.bz2 -O /tmp/sam-1.6.6.tar.bz2 (download and save in /tmp)
b) cd arduino-1.6.7/hardware/arduino/ (Arduino root, here, in my home directory)
c) tar xvfj /tmp/sam-1.6.6.tar.bz2

3. Modify it to read as follows:

@ -76,15 +85,10 @@ The change is near the end, and is the addition of:
"{build.system.path}/CMSIS/CMSIS/Lib/ARM/arm_cortexM3l_math.lib"
On Linux, the path was found to differ slightly (GCC instead of ARM):
"{build.system.path}/CMSIS/CMSIS/Lib/GCC/arm_cortexM3l_math.lib"
Which is the CMSIS AMR3 DSP library for little-endian operation.
4. Save the file and start up the Arduino GUI and build MMDVM.
I would like to get instructions for doing the same on a Linux platform. As a
starter find the relevent platform.txt and try adding:
"{build.system.path}/CMSIS/CMSIS/Lib/ARM/libarm_cortexM3l_math.a"
or maybe:
"{build.variant.path}/libarm_cortexM3l_math.a"
