* Crude support for examining dynamic libraries.
* som.c (som_object_setup): Set DYNAMIC flag for SHL_MAGIC and
DL_MAGIC objects.
(som_prep_headers): Preserve the system_id for DYNAMIC objects.
Use SHL_MAGIC as the magic number of the DYNAMIC flag is set.
Write exec headers for DYNAMIC objects.
(som_begin_writing): DYNAMIC objects have the same alignment
restrictions as D_PAGED objects.
(bfd_section_from_som_symbol): Treat DYNAMIC objects like EXEC_P
objects.
(object_flags): Add DYNAMIC.
