Jim Harris d0a7baa63c mk: add framework for defining inter-lib dependencies
Currently only the iscsi => scsi dependency is defined to
demonstrate how the framework behaves.

Eventually, lib/Makefile will be populated with more lines
of the form:

DEPDIRS-iscsi : scsi log conf event

This line will ensure that the iscsi subdirectory is built
after the specified dependency directories.

Then the lib/iscsi/Makefile also defines:

DEP_LIBNAMES = scsi log conf event

This line adds dependencies from the iscsi.so to the specified
libraries.

Ideally we could avoid this duplication by passing the DEPDIRS
value to the lower level Makefile, but that breaks down when we
start considering event/subsystems/* libraries.  So for now we'll
need to duplicate it.  Incidentally, DPDK also duplicates the
dependency information like this.

While here, remove use of $(MAKESUBDIRFLAGS) in spdk.subdirs.mk -
it was no longer used anywhere in the tree.
