This causes failures in gclient runhooks on 32 bit machines:
https://build.chromium.org/p/chromium.win/builders/Win7%20%2832%29%20Tests/builds/10626
Log snippet:
running 'E:\b\depot_tools\python276_bin\python.exe src/build/linux/sysroot_scripts/install-sysroot.py
Unrecognized host arch: x86
Original issue's description:
> PPC/s390: [sysroot installer] Disable for host arch PPC/s390
>
> Since PPC/s390 doesn't have the sysroot files available
> on google storage, disabling it so that the script doesn't
> cause gclient sync to fail when run on PPC/s390.

OCTEON II boards like the Edge Router Pro are actually MIPS64
processors. So, platform.machine() reports them as "mips64".

We ran "python detect_host_arch.py" ~15 times from gyp. Run
detect_host_arch.py directly from from within gyp for faster execution
and since the path is no longer part of the command, the result will
also be cached more often.
The total gain is at best 0.3 seconds. For most people it will be less.
