* commit 'acb0dea27efff4b35796015b96570b59fd517078': build: Split logic for building examples off into a separate Makefile We already have a Makefile in doc/examples, but it's separate from the build system and meant to be installed as part of the documentation to help users compile the installed .c example files. Move it to Makefile.example to make place for the new build system Makefile. Merged-by: James Almer <jamrial@gmail.com>
