It is more complicated then that;
The LFS build method assumes you can RUN the build binaries on the
builders (host in gcc terms) system.
If you want to compile a system for $target then you normally cannot run
the $target binaries so you need to use a different method using a cross
toolchain.. which is outside the scope of (current) LFS imho :)

Linux is like a small snowball rolling downhill. Microsoft is just
waiting down the mountain...
