override the ways listed later.
The commands to list valid values only list the values that the programs
you are running were configured for. If they were configured with
@samp{--with-targets=all}, the commands list most of the available
values, but a few are left out; not all targets can be configured in at
once because some of them can only be compiled ``native'' (on hosts with
the same type as the target system).

A @dfn{target} is an object file format. A given target may be
supported for multiple architectures (@pxref{Architecture Selection}).
It may also have variations for different operating systems or architectures.
Command to list valid values: @samp{objdump -i} (first column).
Sample values: @samp{a.out-hp300bsd}, @samp{ecoff-littlemips}, @samp{a.out-sunos-big}.
