Breakpoint in shared library does not work on mips-irix.
* procfs.c: #include "observer.h". (procfs_inferior_created): New function, moving here the code which unsets the syssgi syscall-exit notifications. (procfs_create_inferior): Remove the code which unsets the syssgi syscall-exit notifications. It is too early to do this here. (_initialize_procfs): Attach the procfs_inferior_created observer.
