Enable linker work around for PPC476FPE errata #46

configname: CONFIG_476FPE_ERR46

Linux Kernel Configuration
└─>Enable linker work around for PPC476FPE errata #46
In linux kernel since version 3.16 (release Date: 2014-08-03)  
This option enables a work around for an icache bug on 476
that can cause execution of stale instructions when falling
through pages (IBM errata #46). It requires a recent version
of binutils which supports the --ppc476-workaround option.

The work around enables the appropriate linker options and
ensures that all module output sections are aligned to 4K
page boundaries. The work around is only required when
building modules.
