Say Y here if you are compiling the kernel on a different
architecture than the one it is intended to run on. This is just a
convenience option which will select the appropriate value for
the CROSS_COMPILE make variable which otherwise has to be passed on
the command line from mips-linux-, mipsel-linux-, mips64-linux- and
mips64el-linux- as appropriate for a particular kernel configuration.
You will have to pass the value for CROSS_COMPILE manually if the
name prefix for your tools is different.
