Some of the ptrace tests require -ptrace when linking:

 /usr/bin/ld: /tmp/ccH32S9w.o: in function `init_child_sync':
 core-pkey.c:(.text+0x1d64): undefined reference to `sem_init'

The targets for these tests are modfied in lib.mk to add the $(OUTPUT)
prefix. The makefile needs to specify that modifying those rules, or
else they do not match and we miss out on the extra flags.
