We don't ship a rootfs, just a sysroot. You need something like
'buildroot' to build a rootfs, the headers and libraries from the
sysroot are only part of it. These are contained in two places. One is
the sysroot tarball that should be in the same directory as the
toolchain. The exact same sysroot is also in the toolchain tarball under
${host}/libc.
Crosstool-ng never built our sysroots, they were produced by a script
that cobbled one together from an old Ubuntu Precise installation. Now
we do build the sysroot that we ship.
