glibc/elf/Makefile
Florian Weimer ce12fc7113 Remove NO_CTORS_DTORS_SECTIONS macro 
This was originally added to support binutils older than version
2.22:

  <https://sourceware.org/ml/libc-alpha/2010-12/msg00051.html>

Since 2.22 is older than the minimum required binutils version
for building glibc, we no longer need this.  (The changes do
not impact the statically linked startup code.)
