The code for __restore and __restore_rt is emitted as an assembly
function with the hidden attribute.

Only code from sigaction.c can access those functions.

Your options are:
1. Copy them into your shift_sigaction.c file.
2. Remove attribute_hidden from the declarations of the variables, but
beware of name collisions.

Cheers,
Carlos.
