The most recent cross-toolchain-base build was built against glibc 2.24,
but sid has 2.25 now. If libc6-dev:$DEB_HOST_ARCH happens to be
installed (which is necessary for many packages), bad linker errors tend
to happen, e.g.:

//lib/aarch64-linux-gnu/libdl.so.2: undefined reference to `_dl_catch_error@GLIBC_PRIVATE'

This is because the cross gcc mixes the glibc from the sysroot (2.24)
with the one from the system (2.25) in bad ways. I know you'll be
updating cross-toolchain-base soon, but I need a bug number for
tracking.
