[PATCH v3 6/6] containers/Makefile: Makefile to automate builds

[ohilyard@iol.unh.edu]

From: Owen Hilyard <ohilyard@iol.unh.edu>

The Makefile that can be used to build all of the container images using
"make build", and can also be used to push them to a remote repository
(for use in CI).

+# Recommended Resources:
+#	All:
+# 		~100 GB of disk space: These are not minimal containers, they 
+# 							   have full distros in them minus the kernel.
+#							   With ABI images, expect 10 GB per distro per 
+#							   platform. Without, it's closer to 2 GB per distro
+#							   per platform. 
+#
+#	No ABI:
+#		Serial Build (make -j 1): Should run on any post 2010 system reasonably well.
+# 		Parallel build (make -j $(nproc)): 1 GB of free ram per job should be good enough.
+#	ABI:
+#		Time: If you are building more than four distros, or you have one distro that is built under
+#			  emulation (x86 host + arm container or the inverse), it may be best to run it overnight.
+#			  Some versions of qemu + podman will try to compile with a single thread under emulation,
+#			  which can cause what should be an hour-long compile to turn into a 8+ hour compile.
+#		Serial Build (make -j 1): 6 GB of free ram should be fine
+#   	Parallel build (make -j $(nproc)): 6 GB of free ram per job. You may be compiling ~20 versions of DPDK at the same time, with some under emulation.
