[arch-dev-public] Toolchain changes

In my ongoing quest to bring packages to being as vanilla as possible, I
have made some adjustments to the toolchain. These are nothing that
anybody should notice, but I though it worth a post here.
1) /lib and /lib64 symlinks have been moved from glibc to the filesystem
package. Also a /usr/lib64 symlink has been added (see below).
This will make updates more difficult (though not impossible) for those
who do not have the /lib symlink yet. But if you have not upgraded in
over six months, why do you use a rolling release? The workaround I
provided of temporarily using a glibc-2.16 package without the lib
symlink is in the process of dying anyway with packages build built with
2) The "pure64" patch has been removed from glibc. Well, part of it. I
added a sed to keep the 64bit system library directory as /lib. Even
though /lib64 is effectively the same, pacman-4.0 can not handle that well.
This changes the ELF interpreter on x86_64 from
/lib/ld-linux-x86-64.so.2 to /lib64/ld-.... Again, symlinks make this
3) I do not adjust the paths in ldd any more - this required the
/usr/lib64 for it to keep working. The /lib64 symlink is not enough as
I configure glibc to use /usr/lib as its system library directory.
4) ldconfig gets a symlink in /usr/bin. This will probably be helpful
in the future when /sbin dies. Also, I do not remove the default of
ldconfig searching /usr/lib /usr/libx32 /usr/lib64, so "ldconfig -v"
will complain about /usr/lib64 being given more than once as it is
/usr/lib (and any other directory added in ld.so.conf) and about
/usr/libx32 being absent. I might see if this can be fixed through
adding a configure option upstream, but given no-one will probably
notice it is not worth fixing.
Wouldn't it be great if everything was just ./configure; make; make
tl:dr; things will get more difficult for those who have not updated in
six months, but no-one should notice any other change.
