Issue 6226 - Use mesonbuild as a build system

+# A quick note about the terms.
+# -HOST_MACHINE is the machine we build on.
+# -TARGET_MACHINE is the machine we build for (like the Android phone)
+#
+# However, meson use the GNU terms where build_machine is HOST_MACHINE,
+# host_machine is TARGET_MACHINE, and target_machine isn't relevant here
+# since we are not building a compiler.
+# See http://mesonbuild.com/Cross-compilation.html for details
+#
+# We will not use the meson (GNU) terms, unless stricly necessary.
