It's not unexpected that you think of Windows here, but my thoughts
were more towards building from sources on a CD or DVD, where iirc
execute permissions also don't exist. The latest when we have
out-of-tree builds fully working, this ought to be something that
people should be able to do, imo. (Even without out-of-tree builds,
my "next best" alternative of using a tree of symlinks to build in
would similarly have an issue with the links pointing at a mounted
CD/DVD, if the $(SHELL) wasn't present.)
