Author: bdrewery Date: Wed Oct 14 04:42:05 2015 New Revision: 289286 URL: https://svnweb.freebsd.org/changeset/base/289286 Log: Follow-up r288218 by ensuring common objects are built before recursing. Some example where this is a problem: lib/atf/libatf-c++/tests/Makefile:SRCS.${_T}= ${_T}.cpp test_helpers.cpp lib/atf/libatf-c++/tests/detail/Makefile:SRCS.${_T}= ${_T}.cpp test_helpers.cpp lib/atf/libatf-c/tests/Makefile:SRCS.${_T}= ${_T}.c test_helpers.c lib/atf/libatf-c/tests/detail/Makefile:SRCS.${_T}= ${_T}.c test_helpers.c lib/libpam/libpam/tests/Makefile:SRCS.${test} = ${test}.c ${COMMONSRC} A similar change may be needed for FILES, SCRIPTS, or INCS, but for now stay with just SRCS.
