Christophe Leroy 3091f5fc5f powerpc: Mark .opd section read-only
.opd section contains function descriptors used to locate
functions in the kernel. If someone is able to modify a
function descriptor he will be able to run arbitrary
kernel function instead of another.

To avoid that, move .opd section inside read-only memory.
