* 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.

* ld-elfvers/vers1.c: Add missing prototypes and include

# Look for big-endian or little-endian switches in the multlib

# we cannot rely upon proc process_multilib_options to do this
# for us because for some targets the compiler does not support
# -EB/-EL but it does support -mbig-endian/-mlittle-endian, and
# the site.exp file will include the switch "-mbig-endian"
# (rather than "big-endian") which is not detected by proc
# process_multilib_options.
