Linux threads were removed about 12 years ago and the current
nptl implementation only requires 4-byte alignment for pthread
locks.
The 16-byte alignment causes various issues. For example in
building ignition-msgs, we have:
/usr/include/google/protobuf/map.h:124:37: error: static assertion failed
124 | static_assert(alignof(value_type) <= 8, "");
| ~~~~~~~~~~~~~~~~~~~~^~~~
This is caused by the 16-byte pthread lock alignment.
