cogl: ensure we can build on armv4
Without this patch cogl will not build for armv4 as it uses an unsupported instruction. This changeset adds a patch from Wolfgang Denk to add an extra guard around armv5 or above code.

+GCC will define __ARM_ARCH_4T__ when building with "-march=armv4t" so we can
+check this to turn off the use of 'clz' instructions, which otherwise would
+cause compile errors like "selected processor does not support ARM mode
+`clz r3,r0'".
