A pointer to an alternative bfd_target in case the current one is not
satisfactory.  This can happen when the target cpu supports both big
and little endian code, and target chosen by the linker has the wrong
endianness.  The function open_output() in ld/ldlang.c uses this field
to find an alternative output format that is suitable.

Data for use by back-end routines, which isn't generic enough to belong
