nptl: restore .interp section in libpthread.so
In commit 02657da2cf4457804ed938ee08b8316249126444, .interp section
was removed from libpthread.so. This led to an error:
$ /lib64/libpthread.so.0

#0 0x00000000000055a6 in _exit@plt ()
Unfortunately, there is no way to add a regression test for the bug
because .interp specifies the path to dynamic linker of the target
system.
[BZ #18479]
* nptl/pt-interp.c: New file.
* nptl/Makefile (libpthread-routines, libpthread-shared-only-routines):
Add pt-interp.
[$(build-shared) = yes] ($(objpfx)pt-interp.os): Depend on
$(common-objpfx)runtime-linker.h.
