[libstdc++] define zoneinfo_dir_override on vxworks
VxWorks fails to load kernel-mode modules with weak undefined symbols.
In RTP mode modules, that undergo final linking, weak undefined
symbols are not a problem.
This patch adds kernel-mode VxWorks multilibs to the set of targets
that don't support weak undefined symbols without special flags, in
which tzdb's zoneinfo_dir_override is given a weak definition.
for libstdc++-v3/ChangeLog
* src/c++20/tzdb.cc (__gnu_cxx::zoneinfo_dir_override): Define
on VxWorks non-RTP.
