[14] RFR (S) 8236920: 32-bit build failures in libNativeAccess.c

[Aleksey Shipilev]

Bug:
  https://bugs.openjdk.java.net/browse/JDK-8236920

Fix:
  https://cr.openjdk.java.net/~shade/8236920/webrev.01/

This breaks x86_32 test builds. I would like to have this fix in 14.

Testing: Linux {x86_64, x86_32} builds; java/foreign (still passes on x86_64; still fails on x86_32,
seems unrelated to this build breakage); jdk14-submit (still stuck somewhere!)
