This suffers the usual problem of adding a sysdeps test with the same name 
as a non-sysdeps test: it would override nptl/tst-sysconf.c and 
posix/tst-sysconf.c on systems using this sysdeps directory.

Perhaps we should have a naming convention for sysdeps tests, that all 
tests added in sysdeps directories (as opposed to files there that wrap 
non-sysdeps test implementations) include something system-specific in 
their names, so this might be test-powerpc-linux-sysconf.c and linux/ 
tests might be renamed to test-linux-*.c, to avoid accidental overriding.

New tests should be using <support/test-driver.c>.  See:
