I think I cargo cult this.

don't use DEPTH in gyp files. it's only meant for gypi files (where they can be
relative to different places so you can't say "../../" or whatever.

Done.

same here, just ../../../base/base.gyp:base is preferred.

crashpad's would probably be better eventually as it drops most of the goop and
just keeps a minimal useful set. also, it doesn't change unless we change it.
