This is not only highly recommended, but it's how DPKG and RPM does it
as well.

Ever since "make mrproper" (aka "make Mr. Clean") blew away kernel
libraries that the system also used, I've always used a chroot
environment to build kernels.

You don't want to be mixing build toolchains and run-time toolchains if
you can help it, even if they are the same versions.  For those of us
that cross-compile, it's required.  ;)
