Compilation error due to too long file name on truffle-head

[quezacoatl]

I am getting the following compilation error:

/home/quezacoatl/jruby/truffle/target/generated-sources/org/jruby/truffle/nodes/rubinius/EncodingPrimitiveNodesFactory.java:[189,33] error: error while writing EncodingGetObjectEncoding0Node_: /home/quezacoatl/jruby/truffle/target/classes/org/jruby/truffle/nodes/rubinius/EncodingPrimitiveNodesFactory$EncodingGetObjectEncodingPrimitiveNodeFactory$EncodingGetObjectEncodingPrimitiveNodeGen$EncodingGetObjectEncoding0Node_.class (File name too long)

This looks like this issue #2483 I got when I compiled in encrypted home file system, the alternative branch was OK. Or easier avoid encrypted system for compilation.

Dupe of #2483.
