How to build changes made in "os" directory files?

[Ofir Gordon]

Thank you for the quick response!

Can you please explain what you meant in the last comment?
If I don't need that, how can I implement this change in the code I'm using?
Say, if I want to add code that binds a new created thread to a specific
core (I'm familiar with the c++ code required to do so, but where should I
add it in the hotspot source code?)

Regarding the platform, I'm currently just testing it on a linux x86_64 bit
system, but the plan is to run it on a simulated arm 64bit architecture (I
don't know if it makes any difference for where I do the changes in the
source code).
