+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.
