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?
