Subject: [PATCH] gcc: restore dropped `isl` line
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

I think this was a rebase mishap and causes a ton of rebuilds.

Not sure if we actually need the Darwin condition any more (or to be
using the older `isl` version?), but `master` isn’t the place to
find out :)
