When PAM is enabled, openssh makes its own static versions of pthreads
functions.  But when built with a uclibc toolchain, pthreads.h gets
indirectly included.  The clashing exported and static definitions of
the pthreads functions then cause a compile error.  This patch fixes
the problem by changing the static pthread function names with macros
when the static functions are defined.
