Hi,

Here is a v3 of this series. The major changes from v2 are:

 1. Reflecting the change upstream to the v8.6 tag (which they will not
    do again);

 2. Changing the patches to use _PATH_BSHELL for "/bin/sh"; and

 3. Incorporating all of the powerpc64le fixes, including the 10x higher
    STACK_SAFETY_MARGIN that got the build working for Thiago.

I've also made many of the smaller changes requested.

For convienience, I've also pushed this series to the 'zuo' branch of
https://gitlab.com/philip1/guix-patches and tagged it as
guix-issue-57050-v3 (commit 9b429caf1d9cd6574debcb11065b957874d2a31a).

 -Philip

I'm not quite sure about removing bash-minimal, but otherwise LGTM.

This should probably be zuo-bin-sh.patch.
