Christophe Lyon e8fa729574 linux-user: ARM-FDPIC: Add support for signals for FDPIC targets 
The FDPIC restorer needs to deal with a function descriptor, hence we
have to extend 'retcode' such that it can hold the instructions needed
to perform this.

The restorer sequence uses the same thumbness as the exception
handler (mainly to support Thumb-only architectures).
