+ * 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.
