-From 924c35aab1d0d31e9b651c6403cc7fa352e74242 Mon Sep 17 00:00:00 2001
-From: Michael Jeanson <mjeanson@efficios.com>
-Date: Thu, 16 Jan 2020 10:59:14 -0500
-Subject: [PATCH lttng-ust] Fix: build with -fno-common
-
-GCC 10 will default to building with -fno-common, this inhibits the
-linker from merging multiple tentative definitions of a symbol in an
-archive. Keep only the declaration in the libustsnprintf.la convenience
-library.
