| Subject: fix parallel build of btt and blkiomon |
| |
| rbtree.c is used by both binaries. It is possible that when make -C btt |
| is invoked rbtree.o does not exist yet, but is already schedule by the |
| compilation of blkiomon. That could result in recompiling rbtree.o again |
| for btt/btt. |
| In that case, at install time, make will recompile blkiomon which can |
| fail in gentoo, because CC variable is not overriden by ebuild script at |
| install time. (see https://bugs.gentoo.org/705594) |
| |
| Add a dependency on SUBDIRS to wait for all binary in . to be compiled. |
| It will guarante rbtree.o exists. |
