patch to automake 1.6.3 : bug in aclocal.m4 dependencies when builddir != srcdir

[Karl Chen]

Hi, I believe there is a bug in generating the aclocal.m4 dependencies
when in a build directory.

automake 1.6.3 generates aclocal.m4 dependencies that look like
this:

$(ACLOCAL_M4):  configure.in m4macros/compilers.m4 m4macros/debug.m4 m4macros/helios.m4 m4macros/libtool.m4 m4macros/optimization.m4 m4macros/python.m4 m4macros/warning.m4
        cd $(srcdir) && $(ACLOCAL) $(ACLOCAL_AMFLAGS)

but I believe they should look like this:

$(ACLOCAL_M4):  configure.in $(top_srcdir)/m4macros/btng.m4 $(top_srcdir)/m4macros/compilers.m4 $(top_srcdir)/m4macros/debug.m4 $(top_srcdir)/m4macros/helios.m4 $(top_srcdir)/m4macros/optimization.m4 $(top_srcdir)/m4macros/python.m4 $(top_srcdir)/m4macros/warning.m4
        cd $(srcdir) && $(ACLOCAL) $(ACLOCAL_AMFLAGS)

I guess a dependency needs the "$(top_srcdir)/" only if it
includes a path (thus configure.in doesn't need it, although I don't know
if it's possible to have configure.in not be in the top_srcdir)


Here is a patch to fix it:

Thanks.
