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.

[BZ #16831]
* csu/libc-start.c (LIBC_START_MAIN) [!SHARED]: Call
