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.)
