I assume this make file must be running chmod, not the tests themselves 
as otherwise this issue would have been noticed a long time ago. I 
suspect many people run jtreg directly in their local environment rather 
than the make file.

In any case, these older tests predate build test support for compiling 
native code and probably should be migrated anyway.
