ptxdist is about 'executable documentation' and 'reproducability', which
means that any project specifies the ptxdist version it has been built
with, in order to make things reproducable.

As you can install any ptxdist version in parallel, it is absolutely no
problem to build the toolchain with another ptxdist version than the
BSP.

Having that said, we have recently relaxed the rules for the toolchain a
bit. OSELAS.Toolchain is a bit special in that it uses none of the rules
in ptxdist, just the dependency deduction mechanism. So with reasonably
new ptxdist versions, it is possible to build the toolchains as well.
