+Subject: [PATCH] lib/eventlog/Makefile.in: fix static build without closefrom
+
+Since version 1.9.4 and
+https://github.com/sudo-project/sudo/commit/bd1ca79cca827a92e904f022e49df121931d4ff5,
+when closefrom is not available, libsudo_eventlog.a depends on
+libsudo_util.a. So reflect this dependency in the libtool file to avoid
+the following static build failure of logsrvd:
+
+/bin/bash ../libtool --tag=disable-static --mode=link /home/buildroot/autobuild/instance-1/output-1/host/bin/powerpc-linux-gcc -o sudo_logsrvd logsrv_util.o iolog_writer.o logsrvd.o logsrvd_conf.o -static -Wl,--enable-new-dtags -Wl,-z,relro    ../lib/iolog/libsudo_iolog.la ../lib/eventlog/libsudo_eventlog.la ../lib/logsrv/liblogsrv.la
+/bin/bash ../libtool --tag=disable-static --mode=link /home/buildroot/autobuild/instance-1/output-1/host/bin/powerpc-linux-gcc -o sudo_sendlog logsrv_util.o sendlog.o -static -Wl,--enable-new-dtags -Wl,-z,relro    ../lib/iolog/libsudo_iolog.la ../lib/eventlog/libsudo_eventlog.la ../lib/logsrv/liblogsrv.la
+libtool: link: /home/buildroot/autobuild/instance-1/output-1/host/bin/powerpc-linux-gcc -o sudo_logsrvd logsrv_util.o iolog_writer.o logsrvd.o logsrvd_conf.o -static -Wl,--enable-new-dtags -Wl,-z -Wl,relro  ../lib/iolog/.libs/libsudo_iolog.a /home/buildroot/autobuild/instance-1/output-1/build/sudo-1.9.5p1/lib/util/.libs/libsudo_util.a -lpthread -lz ../lib/eventlog/.libs/libsudo_eventlog.a ../lib/logsrv/.libs/liblogsrv.a
