Auto-sync Upstream commit: ebae2f5a6f971a8f0b6c99e00f9c45ef7433924a
Changes in addition to the sync:
Add a downstream patch[1] to reinstate gconv-modules file and apply
glibc-rh697421.patch after it. Also update spec file to create a new
package glibc-gconv-extra with iconv converter modules that are not
commonly used so that they can be removed in minimal or hardened
installations.
