Accepting request 249235 from home:Andreas_Schwab:glibc

- Update to glibc 2.20 release.
  * Reverted change of ABI data structures for s390 and s390x
  * Support for file description locks is added to systems running the
    Linux kernel
  * Optimized strchr implementation for AArch64
  * The minimum Linux kernel version that this version of the GNU C Library
    can be used with is 2.6.32
  * Running the testsuite no longer terminates as soon as a test fails
  * The am33 port, which had not worked for several years, has been removed
    from ports.
  * The _BSD_SOURCE and _SVID_SOURCE feature test macros are no longer
    supported; they now act the same as _DEFAULT_SOURCE (but generate a
    warning)
  * Optimized strcmp implementation for ARMv7
  * Added support for TX lock elision of pthread mutexes on s390 and s390x
  * All supported architectures now use the main glibc sysdeps directory
    instead of some being in a separate "ports" directory
  * The NPTL implementation of POSIX pthreads is no longer an "add-on"
  * Locale names, including those obtained from environment variables (LANG
    and the LC_* variables), are more tightly checked for proper syntax
  * On x86-64, the dynamic linker's lazy-binding support is now compatible
    with application code using Intel MPX instructions
- Patches from upstream removed
  * nss-dns-memleak.patch
  * sin-sign.patch
  * pldd-wait-ptrace-stop.patch
  * nscd-track-startup-failures.patch
  * powerpc-opt-power8.patch
  * check-pf-alloca.patch
  * getaddrinfo-uninit-result.patch
