Subject: [PATCH] tools: Correct pthread API usage

commit c8c5905f562d56d38da951a4102f1c14a6e32bad
Author: Seija K. <doremylover123@...il.com>
Date: Mon Dec 12 11:08:36 2022 -0500

tools: Correct pthread API usage
For POSIX functions, all that is guaranteed is that
a return value of 0 means success, non-zero otherwise.
Checking for "less than" is a mistake
as the error code numbers can be greater than 0.
