Justin Hibbits f62da49b2f powerpc: Transition to Secure-PLT, like most other OSs
Summary:
PowerPC has two PLT models: BSS-PLT and Secure-PLT.  BSS-PLT uses runtime
code generation to generate the PLT stubs.  Secure-PLT was introduced with
GCC 4.1 and Binutils 2.17 (base has GCC 4.2.1 and Binutils 2.17), and is a
more secure PLT format, using a read-only linkage table, with the dynamic
linker populating a non-executable index table.

This is the libc, rtld, and kernel support only.  The toolchain and build
parts will be updated separately.
