From ba41a28cd526bccde4ec3db0998e1b00d3afc0e2 Mon Sep 17 00:00:00 2001 From: "Arnout Vandecappelle (Essensium/Mind)" Date: Tue, 26 Jul 2022 18:31:14 +0200 Subject: [PATCH] configure.ac: try execinfo in libc before searching libexecinfo execinfo is provided by glibc, so the usual case is that it is part of libc. Do this before starting a redundant search for libexecinfo. This is especially relevant for cross-compilation, where FR_SMART_CHECK_LIB can find an incompatible library.
