Getting Illegal instruction - Building PPC e500

[arrathin]

I can build node in the node-v8.11.3 version. But while run node.js on PowerPC , I get only error "Illegal instruction".

Required some assistance to move forward this issue.

Steps to build
./configure --dest-cpu=ppc --without-snapshot --without-intl --partly-static --debug --gdb
$ make -j6 node

I’m not aware that anyone has successfully got Node.js working on an e500 (the V8 engine uses PPC instructions that are not available on that processor). There’s a few people trying in nodejs/node#30323 if that helps.
