[Bug libstdc++/14697] New: libstdc++ couldn't find 32bit libgcc_s

[hjl at lucon dot org]

When building 32bit libstdc++, I got

checking for shared libgcc... no
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
