GN: remove clang flag for NaCl build.

GN: remove clang flag for NaCl build.

NaCl's version of clang is slightly older than the hermetic version used
in Chrome, and does not support this flag.  NaCl's GN build is not live
in the Chrome tree, yet, but this flag breaks local work to bring it up.

+brettw, don't know if Dirk is in today.

Can you add the comment like in the CL description to the flag? It's not
otherwise clear why this is in a !nacl condition.

LGTM with that.

I actually would add the comment to the code itself, not the CL, but maybe
that's just me.
