Bump for the request for comments.
Also, tweaked bits in the TL;DR.

(for those who didn't read the original post, the suggestion is to
allow "GROUP ( =/lib/libc.so.6 =/lib/libc_nonshared.a AS_NEEDED ( =/lib/ld.so.1 ) )"
where the sysroot would be forced as opposed to "it depends".)

...but requires the sysroot be replicated within the sysroot
(e.g. by a parent-directory-chasing symlink) so your outermost
sysroot directory path component better not have a name-conflict
with a library. :)
