The failure is architecture-independent, it's related to the lack of a compat symbol and the difficulty of checking for that at the Makefile or test level. nptl/tst-stack4 is also a generic failure, I think. misc/tst-sync_file_range is probably a real failure related to argument passing. I think this system call was problematic on other architectures, too. Thanks, Florian (Sorry for the wide Cc: list despite the glibc content.)
