Can you add a bit of context about newlib vs. glibc?  e.g. "Use
nacl_helper_nonsfi executable (the new, newlib-based version of the Non-SFI
runtime) to run Non-SFI nexe, instead of nacl_helper (which uses the older,
glibc-based runtime for Non-SFI mode)..."

And also link to the issue for the newlib switch.

Done.

+// TODO(hidehiko): Make this default and then remove this flag after
+// nacl_helper_nonsfi is supported.
