[PATCH v8] Add pretty printers for the NPTL lock types

[Martin Galvan]

I just tried running the test program on a separate laptop and it
failed to work because it couldn't find the libraries. Ldd still
showed:

linux-vdso.so.1 =>  (0x00007fff611fe000)
libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007fc72fe5e000)
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007fc72fa99000)
/home/martin/glibc/install/lib/ld-linux-x86-64.so.2 =>
/lib64/ld-linux-x86-64.so.2 (0x00007fc7300a3000)

I wonder how that last path got hardcoded there?
