fixup "Create common.make with LOCAL_CFLAGS and friends"
The code wasn't what I had intended, although it was functionally
equivalent. Make it more readable and more robust.

When building with Make on a Unix-like platform (shell and compiler),
auto-detect configurations that may require linking with pthread.
This removes the need for MAKE_THREADING_FLAGS in all.sh.

Create a common.make for definitions that are shared between tests/Makefile
and programs/Makefile, to facilitate maintenance. Start populating it with
CFLAGS/LDFLAGS variables. More to follow in subsequent commits.
Keep library/Makefile independent, at least for the time being.
