Description:
The description is for MTR_BUILD_THREAD is incorrect:

https://dev.mysql.com/doc/dev/mysql-server/latest/PAGE_MYSQL_TEST_RUN_PL.html
...
MTR_BUILD_THREAD	
If set, defines which port number range is used for the server

This is correct:
...
MTR_PORT_BASE	If set, defines which port number range is used for the server

How to repeat:
N/A

Suggested fix:
Correct the description

I found the following:

The variable MTR_PORT_BASE is a more logical replacement for the original variable MTR_BUILD_THREAD. It gives the actual port number directly (will be rounded down to a multiple of 10). If you use MTR_BUILD_THREAD, the port number is found by multiplying this by 10 and adding 10000.

It seems the description is confusing rather than incorrect.
