From eefd95b37e1042992cb07bec1ac3f6dbe199d8f0 Mon Sep 17 00:00:00 2001 From: Haruue Icymoon Date: Fri, 22 Nov 2019 16:58:59 +0800 Subject: [PATCH] erofs-utils: fix configure.ac ./configure will fail when --with-lz4-libdir is not set, since $with_lz4_libdir will be an empty string and generate an empty -L into LDFLAGS. This patch fixes it.
