* procfs.c (proc_set_exec_trap): Under Alpha OSF/1-4.0, tracing
the entry to the exit system call to detect termination of the inferior stopped working. Trace termination of the inferior via PRFS_STOPTERM instead. (procfs_init_inferior): Do not trace entry to exit system call if PIOCSSPCACT is defined. (procfs_wait): Handle PR_DEAD event, which signals the termination of the inferior if PRFS_STOPTERM is set. * mdebugread.c (parse_partial_symbols): Ignore stNil section start address symbols. * sparc-tdep.c (get_saved_register): Get saved PC from the frame info if not in innermost frame.

Correct for pc-linux-gnu problem in config.guess.
