Chris Manchester 8ffd9ff2ed Bug 1218999 - Back out changeset 5f32b2bcfa43 (bug 1188468) in favor of a more efficient solution. r=glandium
Bug 118468 landed an option for FileAvoidWrite to always write to an output
file, whether or not the contents would be changed. This was to address a
problem caused by not updating mtimes when building GENERATED_FILES, but
undoes the purpose of FileAvoidWrite and isn't really necessary.
This is addressed in a subsequent commit by unconditionally updating
mtimes when processing GENERATED_FILES.
