Hmm, AdjustOOMScore() is a Linuxism.  We don't have /proc in a NaCl sandbox, so
this function will fail there.

When is AdjustOOMScore() defined?  base/process/memory_stubs.cc defines a no-op
implementation, but it's not referenced by any build files. :-(

Can you add a TEST= line to say how you tested this change, please?

I think this was a leftover from a linking error, but with a more recent
re-build, appears to no longer be necessary.

 BASE_EXPORT extern size_t g_oom_size;
 
 // The maximum allowed value for the OOM score.
