By default, 'RTDLLIST' in 'ldd' refers to 'lib64/ld-linux-x86-64.so', whereas
it's in 'lib/' for us. This patch fixes that.

The format of locale data can be incompatible between libc versions, and
loading incompatible data can lead to 'setlocale' returning EINVAL at best
or triggering an assertion failure at worst. See
https://lists.gnu.org/archive/html/guix-devel/2015-09/msg00717.html
for background information.
To address that, this patch changes libc to honor a new 'GUIX_LOCPATH'
variable, and to look for locale data in version-specific sub-directories of
that variable. So, if GUIX_LOCPATH=/foo:/bar, locale data is searched for in
/foo/X.Y and /bar/X.Y, where X.Y is the libc version number.
That way, a single 'GUIX_LOCPATH' setting can work even if different libc
versions coexist on the system.
