lines.
* nptl/Makefile: Move rules adding libpthread.so and libpthread.a to
link lines to...
* sysdeps/pthread/Makefile: ... here.

Rename
tst-popen1.c -> tst-pt-popen1.c
tst-align.c -> tst-pt-align.c
tst-align3.c -> tst-pt-align3.c
tst-sysconf.c -> tst-pt-sysconf.c
tst-tls1.c -> tst-pt-tls1.c
tst-tls2.c -> tst-pt-tls2.c
tst-vfork1.c -> tst-pt-vfork1.c
tst-vfork2.c -> tst-pt-vfork2.c
to avoid conflicting with libio/tst-popen1.c, elf/tst-align.c,
posix/tst-sysconf.c, elf/tst-tls1.c, elf/tst-tls2.c, posix/tst-vfork1.c,
posix/tst-vfork2.c.

* nptl/Makefile: Move corresponding tests references and special rules to...
* sysdeps/pthread/Makefile: ... here.

* sysdeps/pthread/tst-stack1.c (do_test): Do not clamp stack size to
PTHREAD_STACK_MIN if not defined.

Tested on linux-x86_64 and hurd-i386
