For Sunos 4.x targets, enable gdb to set breakpoints in shared

Browse source 
library functions before the executable is run. Retrieve dynamic
	symbols from stripped executables.
	* symtab.h (minimal_symbol_type):  Add mst_solib_trampoline type.
	* parse.c (write_exp_msymbol), symmisc.c (dump_msymbols),
	symtab.c (list_symbols):  Handle mst_solib_trampoline.
	* minsyms.c (lookup_minimal_symbol):  Handle mst_solib_trampoline
	for all targets, remove IBM6000_TARGET dependencies.
	* dbxread.c (read_dbx_dynamic_symtab):  New function.
	* dbxread.c (dbx_symfile_read):  Use it.
	* dbxread.c (SET_NAMESTRING):  Set namestring to
	"<bad string table index>" instead of "foo" if the string index is
	corrupt.
	* xcoffread.c (read_xcoff_symtab):  Use mst_solib_trampoline instead
	of mst_unknown.
	* symtab.c (list_symbols):  Take from_tty as parameter and pass it
	to break_command. Handle mst_file_* minimal symbol types.
