Split AR_RC into AR and ARFLAGS. The variables AR and ARFLAGS are de-facto standards (like CC and CFLAGS, LD and LDFLAGS, etc.) that may be overridden when running make. Moreover, configuring CC, LD, AR, etc., to point to a cross-platform compiler, linker, librarian, etc., is a de-facto standard practice as well. Also remove the MKDIR_P variable definitions from all makefiles. They've been leftovers from the removal of the "install*" targets.
