Add GYP as a target type that requires 2nd arch.

"GYP" class targets are used by external/chromium_org for gyp's "none"
type. The processing in these targets needs a separate intermediate
directory for the primary/secondary architecture, so add it to the list
in intermediates-dir-for along with libraries/executables.
