OK, so how do I get those tests build?

I did a checkout of glibc.git

glibc$ mkdir build; cd build
build$ ../configure --disable-sanity-checks ; make -j40
build$ ./nptl/tst-robustpi8
-bash: ./nptl/tst-robustpi8: No such file or directory

"make tests" doesn't seem to work either even though its a build target
listed in the Makefiles.

What magic incantation do I need?
