Pulling in https://codereview.chromium.org/2019133002/ in its current
state, as gyp seems to be largely abandoned as a project.
Original commit message:
Hash intermediate file name to avoid ENAMETOOLONG
Hash the intermediate Makefile target used for multi-output rules
so that it still works when the involved file names are very long.
Since the intermediate file's name is effectively arbitrary, this
does not come with notable behavioural changes.
The `import hashlib` boilerplate is taken directly
from `xcodeproj_file.py`.
Concretely, this makes the V8 inspector build currently fail when long
pathnames are involved, notably when using ecryptfs which has a lower
file name length limit.
