emacs 21.3: -h flag to tar not supported on BSD/OS

emacs 21.3: -h flag to tar not supported on BSD/OS

[Jeffrey C Honig]

While importing emacs-21.3 into BSD/OS 4.3/5.0 I found that Makefile.in
and leim/Makefile.in invoke tar with -chf.  The -h flag is not supported
by BSD/OS's tar (which is just a front-end for pax).

I do not see any symlinks in the distribution so I wonder why this flag
is there.

Enclosed is the change I've made.

Thanks.

Jeff

If you build for multiple architectures outside of the source tree,
the area from which you are installing can have symlinks into the
source tree.  Without the -h flag, those symlinks get installed as
symlinks that don't make sense outside the build environment.
