AFAICT, the --enable-64bit configure switch only affects AIX, HP-UX,
IRIX, and Solaris; it has no effect on Linux.

If you want 64-bit code and the compiler defaults to 32-bit, you
probably need to set CFLAGS explicitly before running configure.

I would expect the existing files to be correct for anything which is
part of Ubuntu itself. If Ubuntu packages use /usr/lib64 and it's not
mentioned in /etc/ld.so.conf.d/*, then I'd assume that it's hardwired
into ldconfig (as is the case for /lib and /usr/lib).
