optimizer.exe is run from multiple workers in a chunked fashion. I
would recommend you build emscripten from scratch so you can take
advantage of the latest version.
I would also recommend Ninja over make, but you'll need to switch to a
CMake project, though that has the benefit of being able to generate
both ninja projects and Visual Studio ones from the same source.
the Windows 'emsdk' tool seems to list 1.35.0 as latest.
trying to build the Linux version in WS4L, which has 1.37.1 available.
had to manually upgrade CMake, as the "latest" version it had was IIRC
2.8.1, but LLVM seemed to want a minimum of 3.4.3...
downloaded CMake, now building with 3.7.1, seems to be working, and at
least thus far it doesn't seem I am having to do the usual thing of
chasing down and installing dependencies. the "dependency dance" is IMO
probably one of the main annoyances of trying to rebuild most FOSS stuff
from source.

( this appears to have to do with compiling switch() statements or
similar... )
otherwise:
I have generally had pretty good results with 'make'.
though, for small programs, I have recently sometimes ended up using
batch files or shell-scripts, as a simpler/lighter-weight alternative to
'make' (in some cases, a Makefile is overkill).
