Build breakage on Linux due to 8004188

This change breaks the new build on Linux:

http://hg.openjdk.java.net/jdk8/tl/jdk/rev/44ae777564eb

The build fails with:

make[2]: *** No rule to make target `/u/alanb/ws/tl/jdk/src/share/lib/security/java.security', needed by `/u/alanb/ws/tl/build/linux-x86-normal-server-release/jdk/lib/security/java.security'. Stop.
make[2]: *** Waiting for unfinished jobs....
make[1]: *** [libs-only] Error 2
make: *** [jdk-only] Error 2

We need to get a fix into jdk8/tl or else revert the changes for 8004188.
