node-gyp hard-codes --generator_output to 'build' in PWD directory

[dnwe]

Currently the output of node-gyp is hard-coded to be placed in $PWD/build (in configure.js output_dir = path.resolve('build') (for Windows) and just output_dir = 'build' for unix)

It would be useful if we could specify a custom output directory as a command-line option to node-gyp either via a node-gyp specific option node-gyp configure --build_dir=/tmp/somedir or by allowing us to pass-through our own generator_output parameter to pygyp: node-gyp configure -- --generator_output=/tmp/somedir

Common guys, isn't this a pretty basic request for a build system? (its almost 2017)

2018 checking in. I need to move this location thanks to an issue when dealing with asar package structure.
