[11u] RFR 8250605: Linux x86_32 builds fail after JDK-8249821

[Aleksey Shipilev]

Original fix:
   https://bugs.openjdk.java.net/browse/JDK-8250605
   https://hg.openjdk.java.net/jdk/jdk/rev/1a722ad6e23d

Now that JDK-8249821 is backported to 11u, Linux x86_32 and ARM32 builds fail.

11u variant applies to a different file:
