From 6f1c701026287f6928d3bdd1aea7359308635abe Mon Sep 17 00:00:00 2001 From: Florian Weimer Date: Thu, 3 Jun 2021 08:26:04 +0200 Subject: dlfcn: Cleanups after -ldl is no longer required This commit removes the ELF constructor and internal variables from dlfcn/dlfcn.c. The file now serves the same purpose as nptl/libpthread-compat.c, so it is renamed to dlfcn/libdl-compat.c. The use of libdl-shared-only-routines ensures that libdl.a is empty. This commit adjusts the test suite not to use $(libdl). The libdl.so symbolic link is no longer installed.
