I think you answered this question with "no", when writing in [1]:

  "Even more recently (2018), the GNU C Library glibc-2.28 adds Python
   as a build requirement"

So, how do you avoid Python when building glibc? Do you use musl libc as
a first stage, and only build glibc once a python built with musl exists?

Also, from the diagrams in [1][2][3] it looks like the full-source bootstrap
uses tarballs frozen in time (make-3.80, gcc-2.95.3, gcc 4.7.3, etc.). So,
even if newer versions of 'make' or 'gcc' will use a Python-based gnulib-tool,
there won't be a problem, because the bootstrap of these old tarballs will
be unaffected.
