-         Cause the compiler to optimize for the PPE of the Cell Broadband

-         the scheduling of instructions, not the selection of instructions
-         itself, so the resulting kernel will keep running on all other
-         machines.

+         This symbol controls whether we build the 32-bit VDSO. We obviously
+         want to do that if we're building a 32-bit kernel. If we're building
+         a 64-bit kernel then we only want a 32-bit VDSO if we're building for
+         big endian. That is because the only little endian configuration we
+         support is ppc64le which is 64-bit only.
