[big endian] Unbreak graphics/sane-backends

[Charlene Wendling]

Hi,

I've spotted that sane-backends is broken in the current sparc64 bulk:

> genesys/low.cpp:544:9: error: 'depth' was not declared in this scope
>     if (depth == 16) {

Upstream has already a fix for that [0], it's pending merging.

The below diff fixes the build on powerpc [1]. I bumped REVISION, but
the impacted code only impacts BE_ARCHS and sparc64 is the first arch
building that new sane-backends, i guess it can be omitted.

Comments/feedback are welcome,

Charlène.
