From e47de5cb2d4dbecb58f569ed241e8e95c568f03c Mon Sep 17 00:00:00 2001
From: Florian Weimer <fweimer@redhat.com>
Date: Fri, 29 Apr 2022 16:37:51 +0200
Subject: [PATCH] Do not use --hash-style=both for building glibc shared
objects
The comment indicates that --hash-style=both was used to maintain
compatibility with static dlopen, but we had many internal ABI
changes since then, so this compatiblity does not add value anymore.
