Roll buildtools to 31d4da

Roll buildtools to 31d4da

This CL rolls in the following changes:
https://chromium.googlesource.com/chromium/buildtools/+/3b8de5198d784fe2b7cc9f75dcf2ca8eb616a81e..31d4daad5d9af672d4e234570a24f3fd844bb713

The last reference to //build/config/compiler:pthread is removed, so
this CL also removes the config.
