From memory the change here (s/>&/>/) was necessary to get the build to
succeed - did we ever figure out why that was? I'm not enough of a shell
guru to grok the difference.

Using >& redirects stdout and stderr, whereas > only redirects stdout.

So possibly it doesn't fix anything, but rather lets you see any error
emitted by the compiler rather than swallowing it?
