# Both libsyslog and syslogd/logger require objects like lib/pidfile.o.
# For libsyslog_la, the object files should be compiled with -fPIC, but
# for syslogd and logger these object files should not be compled with
# -fPIC.  There is a race issue when the two different lib/pidfile.o are
# compiled at the same time, which cause errors like:
#
#  ld: syslogd-syslogd.o: in function `main': syslogd.c:417: undefined
#      reference to `__pidfile'
#
# Work around the problem by make LIBOBJS depend on libsyslog.la,
# so that LIBOBJS/syslogd/logger will start compile after libsyslog.la
# is completed
