  build: Update the makefiles for the benefit of cross-compilation
  
  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.
