The usual pattern when supporting a NaCl (untrusted) build is to create a .gypi
file with common stuff, and then .gyp files for normal and untrusted builds.
base/base.gypi and ipc/ipc.gypi and associated .gyp files are good examples. You
can also look in ppapi/ for more.

Specifically it worries me to include this in the same .gyp file as the trusted
target. It may work today but break tomorrow.
