Problem building graal on x86

[Andrew Haley]

I'm still getting:


> Caused by: java.lang.IllegalAccessError: superinterface check failed: class org.graalvm.compiler.api.runtime.GraalJVMCICompiler (in module org.graalvm.compiler.graal_core) cannot access class jdk.vm.ci.runtime.JVMCICompiler (in module jdk.vm.ci) because module jdk.vm.ci does not export jdk.vm.ci.runtime to module org.graalvm.compiler.graal_core

even with a b148 build.

I'll go back to b143 and see what happens.

I guess there's a possibility that I'll have to figure out to fix Jigsaw-
caused bugs.

Andrew.
