+	* lib/ld-lib.exp (proc big_or_little_endian): New proc.
+	Determine if a big endian or little endian output format hass
+	been selected by any of the multilib options, and if so return
+	a suitable command line option for the linker/assembler.
+	(proc default_ld_link): Include the result of proc
+	big_or_little_endian on the command line to the linker.
+	(proc ld_simple_link): Include the result of proc
+	big_or_little_endian on the command line to the linker.
+	(proc default_ld_compile): Append multilib flags to compiler
+	switches.
+	(proc default_ld_assemble): Include the result of proc
+	big_or_little_endian on the command line to the linker.
