nodejs/node#3962 enabled snapshots in Node however this doesn't seem to work with the ARM cross-compiler, as seen in https://ci.nodejs.org/job/node-cross-compile/588/nodes=cross-compiler-pi1p/console

/home/iojs/build/workspace/node-cross-compile/nodes/cross-compiler-pi1p/out/Release/mksnapshot: 1: /home/iojs/build/workspace/node-cross-compile/nodes/cross-compiler-pi1p/out/Release/mksnapshot: Syntax error: word unexpected (expecting ")")

I changed the node-cross-compile to pass --without-snapshot to configure, so that we can continue running CI while we figure the best long-term approach.

A few questions:

1. Is it absolutely impossible to produce a snapshot on the build platform, if it's different from the target platform? Or is it just a limitation in the compiler?
2. Are ARM release builds coming out of the cross-compile job?
3. Can we live without snapshots for ARM?
