From d2db60d8d830ef68c8d20a77ac3572d610aa40b1 Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Mon, 21 Feb 2022 13:52:20 -0300 Subject: Remove dl-librecon.h header. The Linux version used by i686 and m68k provide three overrrides for generic code: 1. DISTINGUISH_LIB_VERSIONS to print additional information when libc5 is used by a dependency. 2. EXTRA_LD_ENVVARS to that enabled LD_LIBRARY_VERSION environment variable. 3. EXTRA_UNSECURE_ENVVARS to add two environment variables related to aout support. None are really requires, it has some decades since libc5 or aout suppported was removed and Linux even remove support for aout files. The LD_LIBRARY_VERSION is also dead code, dl_correct_cache_id is not used anywhere. Checked on x86_64-linux-gnu and i686-linux-gnu.
