This causes the following build warning in chrome/mac:


[560/11003] LIBTOOL-STATIC libwebp_dsp_neon.a, POSTBUILDS
libtool: warning for library: libwebp_dsp_neon.a the table of contents is empty
(no object file members in the library define global symbols)


We try very hard to be warning-free, and this is now our only build warning. Can
you please take a look? One possible technique, used by a neon target in webkit,
is to make this target type 'none' on non-neon platforms. Here's how this is
done in third_party/WebKit/Source/WebCore/WebCore.gyp:

            ['include', 'platform/graphics/filters/arm/.*NEON\\.(cpp|h)'],

          ],
        },{  # target_arch!="arm"
          'type': 'none',
