angular: bug(build) Build broken when doing a clean checkout and following Developer-Explanations

Steps to reproduce and a minimal demo of the problem

Doing a clean checkout of angular leads to several errors when trying to build angular from master. Doing

 git clone https://github.com/angular/angular.git
 npm i
node --max_old_space_size=4000 ./node_modules/.bin/gulp build.js

leads to

[10:24:03] Finished 'build/clean.bundles.benchpress' after 4.45 ms

as the typings are not installed via tsd in the tools folder. Doing a manual tsd install in tools folder then leads to further errors when executing the build:

creating this folder manually and running the build leads to:

    at Array.forEach (native)

then I gave up…

Expected/desired behavior

Build of a clean checkout should be possible just following the Developer Guidelines:

https://github.com/angular/angular/blob/master/DEVELOPER.md
