Arches, please test and mark stable media-libs/libexif-0.6.16-r1.

Stable for sparc, all tests pass as expected.

media-libs/libexif-0.6.16-r1  USE="nls -doc"

1. Emerges on AMD64. 
2. No collisions and passes test. 
3. Works - gimp depends on it and is still working. 

Please mark stable on AMD64.
