coreutils src/Makefile.am fixes for Solaris 8 'make' problems

[Paul Eggert]

"make check" failed on Solaris 8 sparc because Solaris 8 'make'
wouldn't build the groups file: it saw the line "groups: Makefile" and
decided that was enough.  I also noticed a lot of needless rebuilding
of localedir.h, which I think I've seen on other platforms too: that
makefile rule is well-intentioned but ineffective since $(localedir)
might be set outside Makefile -- in general, if Makefile changes you
gotta rebuild everything from scratch anyway.  I installed this patch.

2004-07-28  Paul Eggert  <address@hidden>

        * src/Makefile.am ($(SCRIPTS)): Don't depend on Makefile;
        this causes Solaris 8 'make' to refuse to build "groups".
        (localedir.h): Don't depend on Makefile: this causes Solaris
        8 'make' to build localedir.h unnecessarily.  The dependence
        on Makefile is ineffective anyway, since $(localedir) might
        change even if Makefile hasn't.
