[Buildroot] [PATCH] stress: honor the BR2_PREFER_STATIC_LIB preference

[Tzu-Jung Lee <roylee17@gmail.com>]

From: roylee17 <roylee17@gmail.com>

Stress is linked statically if the --enable-static is specified.
However, this option is always specified in the global
SHARED_STATIC_LIBS_OPTS to tell packages to build static libraries,
if supported.

If the BR2_PREFER_STATIC_LIB is not defined, we have to specify
--disable-static explicitly to get stress linked dynamically.
