Marc Hartmayer 0f87acc2b3 common.mak: Improve overall Makefile performance ...

Improve overall Makefile performance by dramatically reducing the number
of fork and exec system calls through the use of simply expanded
variables [1]. Before this change, a simple `make -C libutil` invocation
used over 4000 execs, after this change it was reduced to just over 300
execs.
