Commit Message

Adhemerval Zanella Netto May 10, 2021, 5:04 p.m. UTC 
The nptl version is used as default, since now with symbol always
present the single-thread optimization is tricky.

Hurd is not change, it is used it own lock scheme (which call
_cthreads_flockfile).

Checked on x86_64-linux-gnu.
