Emergency patch from libc-alpha.
From: Siddhesh Poyarekar <siddhesh@sourceware.org>
Subject: [PATCH v2] iconvconfig: Fix multiple issues
To: libc-alpha@sourceware.org
Cc: schwab@linux-m68k.org, fweimer@redhat.com
Date: Fri, 25 Jun 2021 14:31:28 +0530
Message-Id: <20210625090128.316837-1-siddhesh@sourceware.org>
It was noticed on big-endian systems that msgfmt would fail with the
following error:
msgfmt: gconv_builtin.c:70: __gconv_get_builtin_trans: Assertion `cnt < sizeof (map) / sizeof (map[0])' failed.
Aborted (core dumped)
This is only seen on installed systems because it was due to a
corrupted gconv-modules.cache. iconvconfig had the following issues
(it was specifically freeing fulldir that caused this issue, but other
cleanups are also needed) that this patch fixes.
- Add prefix only if dir starts with '/'
- Use asprintf instead of mempcpy so that the directory string is NULL
terminated
- Make a copy of the directory reference in new_module so that fulldir
can be freed within the same scope in handle_dir.

nptl: Export libthread_db-used symbols under GLIBC_PRIVATE
This allows distributions to strip debugging information from
libc.so.6 without impacting the debugging experience.
nptl_version had to be renamed to __nptl_version to avoid
namespace issues.

nptl_db: Install libthread_db under a regular implementation name
Currently, the name is always libthread_db-1.0.so. It does not change
with the glibc version, like the other libraries.
GDB hard-codes libthread_db.so.1 (the soname), so this change does not
affect loading libthread_db.
Tested on x86_64-linux-gnu, in an environment where the nptl GDB tests
actually run.

Makerules: Remove lib-version, $(subdir-version)
Also clarify that the “versioned” term refers to the soname, not the glibc
version (which also ends up in the installed file name).
I verified on x86_64-linux-gnu that “make install” produces the same
files.

Install shared objects under their ABI names
Previously, the installed objects were named like libc-2.33.so,
and the ABI soname libc.so.6 was just a symbolic link.
The Makefile targets to install these symbolic links are no longer
needed after this, so they are removed with this commit. The more
general $(make-link) command (which invokes scripts/rellns-sh) is
retained because other symbolic links are still needed.
