Subject: [PATCH] stress-pthread: fix non-NPTL build

https://github.com/ColinIanKing/stress-ng/commit/15b26e33daaf36acd5eeceaaf6fc954f46792a8b
added the usage of attr without using HAVE_PTHREAD_ATTR_SETSTACK for
toolchains without NPTL support.

This patch fixes build errors detected by buildroot autobuilders:
