For goal "all", we do it the nice way: "all" has a prerequisite subdir-T for each T in $(TARGET_DIRS), and T's recipe runs make recursively. Behaves nicely with -j and -k. For other goals such as "clean" and "install", the recipe runs make recursively in a for loop. Ignores -j and -k. Generalize the recursion machinery used by "all" so we can reuse it for "clean" and "install". This was previously posted as PATCH 1-4 of "[RFC v4 0/7] Baby steps towards saner headers". Changes since then: * PATCH 1: Don't lose @ [Philippe] * PATCH 3: Update check-report-qtest-%.tap [Philippe] Markus Armbruster (4): Makefile: Remove code to smooth transition to config.status Makefile: Drop bogus cleaning of $(ALL_SUBDIRS)/qemu-options.def Makefile: Rename targets for make recursion Makefile: Reuse all's recursion machinery for clean and install Makefile | 73 ++++++++++++++++++++---------------------- configure | 6 ++-- tests/Makefile.include | 5 +-- 3 files changed, 40 insertions(+), 44 deletions(-)
