cd ~
mkdir .gyp
nano .gyp/include.gypi
paste the following
{
'variables': {
'linux_use_gold_binary' : 0,
'linux_use_gold_flags' : 0,
'target_arch': 'arm',
'disable_nacl': 1, # NaCL does not build for ARM.
'linux_use_tcmalloc': 0, # tcmalloc does not build for ARM.
'armv7': 1, # Optional, for targeting ARMv7.
'arm_thumb': 1, # Optional, for targeting thumb. Combine with armv7 to target thumb2.
'arm_neon': 1, # Optional, to disable NEON. 1 is the default, and most people want to keep it that way.
'verbose': 1,
'arm_float_abi': 'hard',
'use_system_yasm': 0,
'werror' : ''
}
}

-Save
 
nano arm.env
paste the following
export CXX=g++
export CC=gcc
export AR=ar
export AS=as
export RANLIB=ranlib
export CFLAGS=""
export CCFLAGS=$CFLAGS
export CXXFLAGS=""
export GYP_DEFINES="target_arch=arm"
export GYP_GENERATORS="make"
 
-Save 
 
source  ~/arm.env
 
create a 3gb swap file (google how tondo this if you dont know)
 
-Get the src for node-webkit (i wont document that here)
 
now just run 
make nw -j4 BUILDTYPE=Release

note, make sure you have 'arm_float_abi': 'hard' in your include.gypi as chromium will try to make some of the files using softfp.

Also if cross compiling you dont need to put 
  'linux_use_gold_binary' : 0,
  'linux_use_gold_flags' : 0,
in the include.gypi we need this when compiling natively as the gold linker doesent work on arm
