Fix the order in which we build subdirectories in a "make all" from the top-level release/doc directory.  We were building in share/sgml first, which caused us to autogenerate hardware notes entities in the wrong format (we want to build these via ${RELNOTES_LANG}/hardware/Makefile, in order to get the HWNOTES_MI variable).
