Support _r_debug for static binaries.
We initialize _r_debug for static binaries to allows debug agents to treat static binaries a little more like dyanmic ones. This simplifies the work a debug agent has to do to access TLS in a static binary via libthread_db. Tested on x86_64. See: https://sourceware.org/ml/libc-alpha/2014-04/msg00183.html [BZ #16831] * csu/libc-start.c (LIBC_START_MAIN) [!SHARED]: Call _dl_debug_initialize.
