On the core-updates branch, since commit
5f3f70391809f8791c55c05bd1646bc58508fa2c, bootstrapping fails early for
armhf-linux and aarch64 when trying to build pkg-config (for
python-boot0).  That can be easily worked around with this patch:

But then Python fails at the configure stage because pthreads is not
working with the bootstrap compiler on those platforms.

I'm not sure what to do about it.  I tried using 'python-on-guile' with
this patch:

But the interpreter fails with 'unbound variable: this' upon running
glibcs Python scripts.

Until python-on-guile is complete enough to run the glibc scripts, I
think we'll have to insert an older version of glibc into the
bootstrap graph, so that Python can be built with pthreads on all
platforms.  WDYT?
