Romain Naour e922c1774c package/kvazaar: disable on PowerPC, PowerPC64 and PowerPC64le
kvazaar is affected by three different build issues on PowerPC and
related architectures:

 - On PowerPC64, the build fails due to the use of a deprecated
   vec_lvsl() function:

strategies/altivec/picture-altivec.c: In function ‘reg_sad_altivec’:
strategies/altivec/picture-altivec.c:43:5: error: vec_lvsl is deprecated for little endian; use assignment for unaligned loads and stores [-Werror=deprecated]
perm1 = vec_lvsl(0, &data1[y * stride1]);
^~~~~

   This bug has been reported upstream at:
   https://github.com/ultravideo/kvazaar/issues/172

 - On PowerPC 8548, the build fails due to mixing AltiVec and E500
   instructions:

strategies/altivec/picture-altivec.c:1:0: error: AltiVec and E500 instructions cannot coexist

   This bug has been reported upstream at:
   https://github.com/ultravideo/kvazaar/issues/173

 - On PowerPC e500mc, because Altivec is not supported on this target:

strategies/altivec/picture-altivec.c:1:0: error: AltiVec not supported in this target

   This bug has been reported upstream at:
   https://github.com/ultravideo/kvazaar/issues/174
