["hjl at lucon dot org" <gcc-bugzilla at gcc dot gnu dot org>]

When building 32bit libstdc++, I got

configure: WARNING: === You have requested some kind of symbol versioning, but
configure: WARNING: === either you are not using a supported linker, or you are
configure: WARNING: === not building a shared libgcc_s (which is required).
configure: WARNING: === Symbol versioning will be disabled.
configure: versioning on shared library symbols is no 

It is caused by
