[RFC/PATCH] Install db-Makefile under $prefix

[Jonathan Nieder]

After commit 77fb9117 (Install db-Makefile, 2011-06-15), trying to
install as an unprivileged user with "../configure
--prefix=$HOME/glibc-test && make && make install" fails for lack of
privilege to write files under /var.

"make install" should not be writing files outside of $prefix anyway.
Fix it by using localstatedir (which defaults to $prefix/var) instead
of /var in the path for nss db files.

This is not enough to get nss_db working in configurations with
nonempty prefix, since db-Makefile and the nscd code still hard-code
the absolute path /var/db.  Fixing that can wait for another day.

Hi,

"make install" failed when I tried it today; hopefully this patch can
help.  Probably not usable as-is because distros would need to be
updated to pass

	--localstatedir=/var

Any autoconf experts have hints about where to put logic to set that
up automatically?  Other thoughts?

	* Makeconfig: Prepend $(prefix) to vardbdir by defining the
	latter in terms of localstatedir.
