how to know host endianness in binutils

There is a CYG_AC_C_ENDIAN function in config/acinclude.m4 that defines
LITTLE_ENDIAN_HOST for little endian hosts, but as far as I can tell this
function is never invoked.

Other code seems to rely upon this define too.  For example gdb/tracectf.c.

Also as H.J. mentioned it does appear that the code in the script configure
does do the right thing.  I would suggest that you can safely use it.
