Isn't this defined elsewhere? Yeah, when we decide to move it to
tools/lib/workqueue/ we'll need it, but for now, reduce patch size.

No, it's just statically defined in tools/perf/jvmti/jvmti_agent.c.
I saw there is a libc_compat.h header in tools/include/tools, I could put this
definition there, and remove the one from jvmti_agent.c.

Please, do it as a prep patch.

Thanks,
