        recompile with -mminimal-toc or -fno-optimize-sibling-calls, or make `_restgpr0_28' extern


And those are generated calls so I don't see how we can fix them.

Is this a module ? We should really be linking that stuff directly with the module....

The interesting thing is that we do build everything except a handful of
files with -mminimal-toc unless something's wrong with our main Makefile....

Can you show the full build command that triggers the above ?
