[RFA] Make solib-sunos.c more self-contained

[Mark Kettenis <mark.kettenis@xs4all.nl>]

Most of the remaining lines in the remaining nm-*bsd*.h files consist
of defines for the old a.out shared library support.  It's pretty easy
to autoconf these; we already have a suitable define:
HAVE_STRUCT_SO_MAP_WITH_SOM_MEMBERS.  This patch moves these defines
into solib-sunos.c.

Kevin, d'you have any objections?

Mark

	* solib-sunos.c [HAVE_STRUCT_SO_MAP_WITH_SOM_MEMBERS] (link_map)
	(lm_addr, lm_name, lm_next, link_dynamic_2, ld_loaded, rtc_symb)
	(rtc_sp, rtc_next, ld_debug, ldd_in_debugger, ldd_bp_addr)
	(ldd_bp_inst, ldd_cp, link_dynamic, ld_version, ldd, ld_un, ld_2):
	New defines.
