- Reinstate gconv-modules as the default configuration file
This adds patches proposed upstream to enable downgrades across
major glibc versions.
File list construction and the find-debuginfo.sh wrapper had
to be adjusted to cope with the changed file name patterns.
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.

Upstream commit: ac0353af81a23535f517586a5d04427120a157ac
- This removes libpthread as a separate shared object. New programs
will depend on the GLIBC_2.34 symbol version. Upstream development
brings in the following noteworthy bug fixes:
- ppc64le: scv ABI error handling fails to check IS_ERR_VALUE (#1962971)
- CVE-2021-27645 glibc: Use-after-free in addgetnetgrentX function in
netgroupcache.c (#1932590)
- Linking the main program with jemalloc causes sysconf to deadlock in
audit mode (#1909920)
Glibc on arm has a memory tagging option that can be enabled
via GLIBC_TUNABLES="glibc.mem.tagging=$SOMETHING" when glibc
is built with memory tagging support and the kernel/HW supports
MTE. This should be side effect free unless the user turns it
on with approprate HW support.

This needs a wrapper script around find-debuginfo.sh, so that
ld.so is not stripped.
This commit resolves debuginfo file conflicts (#1886295) because
the ldconfig debuginfo file now includes the architecture name.
All debugging information is preserved in ld.so (#1905611). With
the distribution defaults, we strip all binaries again (#1661510).
