I think you found a problem with the conversion from my off-tree script
to this auto-generated version.
In the off-tree script, the argument to --library-path was hardcoded and
it included the path to nptl_db, as mentioned in the wiki page I used [1]
(look for occurrences of "${GLIBC}/nptl_db:").
In the auto-generated version, I used the makefile expansion of
"$(rtld-prefix)", which I though gave the same path, but I failed to
notice that nptl_db was missing (nptl is there, but not nptl_db).
It should be easy to complement the argument to --library-path. I'll
check if that actually solves the problem (as the wiki [1] seems to
suggest), then send another version of this patch.
Thanks for your careful review! :)
