Bug#612000: libc6: please postinst symlink /usr/local/lib64 -> /usr/local/lib for consistency with /, and /usr ones

[Yaroslav Halchenko <debian@onerussian.com>]

Package: libc6
Version: 2.11.2-9
Severity: minor


Without /usr/local/lib64 symlink to /usr/local/lib  many local installations of
upstream projects (not that I am encouraging such cruel activity) would install
into /usr/local/lib64 on amd64 systems.  Since symlink is not available,
install would create a directory /usr/local/lib64 to place the content;
but default Debian setup of ldconfig does not include any of */lib64
directories, so those libraries would not become readily available.

Having a symlink /usr/local/lib64 -> /usr/local/lib should make our systems
"friendlier" to the users willing sacrificing piece of mind by installing
something 'locally'.
