* cpu-hppa.c (arch_info_struct): Support both PA1.0 and PA1.1
machine types.
(bfd_hppa_arch): Link in both PA1.0 and PA1.1 architecture info
structures.
* libhppa.h (enum pa_arch): New enumeration to describe the
different variants of the PA architecture.
* som.c (som_object_setup): Use new enumeration to set machine
type.
(som_finish_writing): If the machine type is PA1.1, then use the
PA1.1 machine identifier in the output file.
