Commit Message

Adhemerval Zanella Netto March 19, 2021, 8:29 p.m. UTC 
  The libc version is identical and built with same flags.  Both aarch64
and nios2 also requires to export __send and tt was done previously with
the HAVE_INTERNAL_SEND_SYMBOL (which forced the symbol creation).

All __send callers are internal to libc and the original issue that
required the symbol export was due a missing libc_hidden_def.  So
a compat symbol is added for __send and the libc_hidden_def is
defined regardless.

Checked on x86_64-linux-gnu and i686-linux-gnu.

What's the intended compat symbol status of __send with this patch?

Presently, it's a compat symbol on aarch64 and nios2 only, I think.
This is sufficient to avoid the additional of the __send@@GLIBC_2.34
symbol there.  The other architectures already have a public __send
symbol, so the issue does not apply to them.

I think this split approach is okay for now, and as far as I can tell,
this patch achieves it, so I think it should go in.
