[PATCH v2] Use LFS and 64 bit time for installed programs (BZ #15333)

[Florian Weimer]

* Adhemerval Zanella via Libc-alpha:

-D_TIME_BITS=64 does not work for building glibc because the internal
aliases such as __fstat64 do not follow _TIME_BITS and are hard-wired to
32-bit time.  A symptom is a broken ldconfig, e.g.:

$ elf/ldconfig -p
elf/ldconfig: mmap of cache file failed.
: Invalid argument
