nptl/tst-getpid2.c has

---
#define TEST_CLONE_FLAGS CLONE_VM
#include "tst-getpid1.c"
---

which calls clone with CLONE_VM and leads to nptl/tst-getpid2.c fails at
random with "illegal hardware instruction".

    Don't run tst-getpid2 with LD_BIND_NOW=1

    Since _dl_x86_64_save_sse and _dl_x86_64_restore_sse are removed now,
    we don't need to run tst-getpid2 with LD_BIND_NOW=1.

        [BZ #11214]
        * sysdeps/unix/sysv/linux/Makefile (tst-getpid2-ENV): Removed.
