Commit Message

Florian Weimer May 3, 2021, 1:52 p.m. UTC 
  The symbol was moved using scripts/move-symbol-to-libc.py.

A small adjust to the sem_unlink implementation is necessary to avoid
a check-localplt failure.

A placeholder symbol to keep the GLIBC_2.1.1 version alive in
libpthread is added with this commit.
