From 55f41ef8de4a4d0c5762d78659e11202d3c765d4 Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Mon, 6 Nov 2023 17:25:46 -0300 Subject: elf: Remove LD_PROFILE for static binaries The _dl_non_dynamic_init does not parse LD_PROFILE, which does not enable profile for dlopen objects. Since dlopen is deprecated for static objects, it is better to remove the support. It also allows to trim down libc.a of profile support. Checked on x86_64-linux-gnu.
