No functional change.
Rather than tracking both build targets and sub directory to run 'make
install' from, use a make loop for the staging/target install logic, similar
to how we are doing it to for the build step and directly use the Makefile
in the sub directory rather than the helper lib/lz4 targets in the top level
Makefile.
