Matt Weber 0bfc3e915d package/gcc: transition PowerPC 32 to secureplt
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.

Fixes a bug observed when creating SELinux policy where all apps
require execmem because the heap requires execute before this change.
