Cannot install serialport module with npm

Hi

It looks like the installer tries to natively compile some C++ code but cannot find the required tools.
You probably already did install additional packages, e.g. make because the build fails when calling g++.

On a freshly installed V2.4 module I get:

opkg install nodejs nodejs-npm
npm install serialport

.

> serialport@2.0.5 install /home/root/node_modules/serialport
> node-pre-gyp install --fallback-to-build

gyp ERR! build error
gyp ERR! stack Error: not found: make

Installling the build essentials for native compilation works for me.

opkg install packagegroup-sdk-target

.

root@colibri-imx6:~# npm install serialport

> serialport@2.0.5 install /home/root/node_modules/serialport
> node-pre-gyp install --fallback-to-build

make: Entering directory '/home/root/node_modules/serialport/build'
  CXX(target) Release/obj.target/serialport/src/serialport.o
  ...
  TOUCH Release/obj.target/action_after_build.stamp
make: Leaving directory '/home/root/node_modules/serialport/build'
serialport@2.0.5 node_modules/serialport
─ bindings@1.2.1
...
─ nan@2.0.9

Note that I did not test the resulting serialport module.
