/* libpthread used to have its own vfork implementation that differed

   from libc's only in having a pointless micro-optimization.  There

   is no longer any use to having a separate copy in libpthread, but

   the historical ABI requires it.  For static linking, there is no

   need to provide anything here--the libc version will be linked in.

   For shared library ABI compatibility, there must be __vfork and

   vfork symbols in libpthread.so.

   As of GCC 7, microblaze can *not* rely on the compiler to generate

   a tail call from this vfork to __libc_vfork.  */
