make install is pretty broken

[Mark Kettenis <kettenis at wins dot uva dot nl>]

If force-install = no, make install is broken, see the attached bits
from an install log.  The problems are probably caused by the
following patch:

2000-03-17  Cristian Gafton  <gafton@redhat.com>

	* elf/Makefile ($(rtld-version-installed-name)): Delay replacing
	existing rtld-installed-name.
	($(rtld-installed-name)): Request libc-$(version) be installed too.
	replace existing rtld-installed-name using $(symbolic-link-prog).

I don't understand this patch.  It doesn't say what it tries to fix,
and there are no comments in elf/Makefile explaining things.  It
probably tries to deal with overwriting an already installed libc with
a new one with the same version number.  However, I don't see how it
avoids problems, since there is always a window where the old libc.so is
used with the new ld.so, or the other way around.  Can we revert this
patch?
