I guess you're simply confused about the --build/--host naming conventions.

--host ... the platform your binaries are targeting.
--build ... the platform you are running your build-tools on.

i.e. if you are using a cross-toolchain, which is complying to the 
gnu-canonicalization conventions (Native tools without prefix, 
cross-tools with <host>-prefix),

configure --host=arm-eabi
will cross-build for a target named arm-eabi, producing binaries for 
arm-eabi.

--build usually is only needed if you're using some weird host system or 
when Canadian-cross building.
