Subject: [PATCH] build: Make create_build_dir PHONY and add order-only deps

Mark create_build_dir as PHONY so directory creation is never skipped.
Also add html_data.h as order-only prerequisite to the .c pattern rule,
fixing another the race where httpd/httpd.c and httpd/page_impl.c are
compiled before the generated header exists.
