[svn-r1949] Problem:
    The Dependencies files were generated in $srcdir even when
    --srcdir is used.  It caused conflicts if multiple hosts
    are doing make sharing the same $srcdir.  It also violated
    the rule that --srcdir would not modify the content of $srcdir
    which could be on a read-only media like a CD-ROM.
Solution:
    Dependencies files are generated in the "current" directory.
Platform tested:
    dangermouse (linux), modi4 (IRIX64).
