 The makefile is wrong.
 According to make(1) you need .MAKE on targets which are supposed to
 pass on the jobs queue.
 
 What's really odd is that all2 "works"
 If you add .MAKE to all:
 
 make -j8 all 
 --- all ---
 (cd mack && make)
 --- foo1 ---
 --- foo2 ---
 --- foo3 ---
 --- foo4 ---
 --- foo5 ---
 --- foo6 ---
 --- foo7 ---
 --- foo8 ---
 --- foo4 ---
 echo 4
 4
 --- foo9 ---
 --- foo6 ---
 echo 6
 6
 
 etc.
 
 As per log change in 1.173 fixes a serious decriptor leak, 
 which is probably why the makefile in question may have previously
 worked.
