There is a problem with make-3.56 when it is invoked with
the -f option to specify the filename of the makefile which
includes other makefiles for which rules exist.  It saves
the name of the makefile on a list called read_makefiles.
Unfortunately, with the current version this name goes to
the end of the list (which can potentially contain included
makefiles not mentioned with the -f option).  The list of
makefiles included with the -f option (called makefiles) is
is then added to using the first makefile on this list (when
the correct makefile is actually the last one).

I changed the routine read_makefile in read.c to add these
makefiles to the end of read_makefiles rather than the
beginning, so that when the makefile name is saved in
makefiles from the beginning of the read_makefiles list, it
is correct.

Here are the context diffs of the changes I made.  I didn't
see anything else that depended on the order of links in the
read_makefiles list, but if anyone knows of something that
does, please let me know.
