abb5482731 remove Clang warnings with unused arch arguments.
This is duplicating code from compiler flag checking that was once
added (then reverted to CMake) as the problem seem to be on the
clang side as detailed in:
http://public.kitware.com/Bug/view.php?id=13194

I also tried to remove a similar warning with pthreads but there
is also an issue on the clang side:

5ab6d9de1f AnimEncoder: avoid freeing uninitialized memory pointer.
In GenerateCandidates(), when candidate_ll->evaluate_ and
candidate_lossy->evaluate_ are both true, if lossless encoding
exits on error, candidate_ll->evaluate_ would not be correctly
reset. This will cause freeing uninitialized memory pointer in
SetFrame().

f29bf582df WebPAnimEncoder: If 'minimize_size' and 'allow_mixed' on, try lossy + lossless.
This improves compression by ~5% at default quality.

If only 'allow_mixed' is on (but 'minimize_size' isn't), we continue to
use a heuristic to try one of the two or both.
