| /* 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. */ |
