From: "Steven Rostedt (Google)" <rostedt@xxxxxxxxxxx> Instead of adding a test in all the Makefiles that test ZLIB_INSTALLED, just create a variable that has ZLIB_LDLAGS set to -lz when enabled and pass that to the LIB flags. When it's not enabled, ZLIB_LDLAGS will be empty. (I guess LDLAGS should have been LDFLAGS but a typo appears to have gone wild!)
