-/* libpthread once had its own fork, though there was no apparent reason
-   for it.  There is no use in having a separate symbol 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 __fork and fork symbols in
-   libpthread.so.
-
-   With an IFUNC resolver, it would be possible to avoid the
-   indirection, but the IFUNC resolver might run before the
-   __libc_fork symbol has been relocated, in which case the IFUNC
-   resolver would not be able to provide the correct address.  */
