<pre>rewriting nops to toc restores works for big-endian, but not little-endian
ppc64.
Calls that cross dso-boundaries will set r2 to the toc pointer for the dso the
callee resides in. The plt stub will save the local toc pointer into the toc
save slot (sp + 24) and the compiler will have inserted a nop after any call
that may not be local. LLD needs to recognize when a call is not local, and
rewrite the nop to a load of the saved toc pointer into r2.</pre>
