Replacing all occurrences of `/usr` with `/nix` doesn't work, because
one test is just verifying if `wdirname` works (and `dirname /usr/lib`
is not the same as `dirname /nix/lib`).
When the noexec patch was added, this comment should have been moved
to make it clear it referred to the Darwin patch, which was previously
the only one.
When, after patching, `configure.ac` is newer than `configure`, the
Makefile will try to regenerate `configure` from `configure.ac`.
While that might usually be desirable, in this case we want to keep
bootstrapping simple and directly use the `configure` from the package
so we can avoid a dependency on automake.
Previously, we used the `-T` parameter to automake to make sure the
timestamps were okay. However, this is brittle when we update: when the
timestamp of the original file changes, and no longer matches the
timestamp of the original file in the patch, `patch` will show a warning
but otherwise continue without updating the timestamp.
This PR changes things so we only patch `configure`, so that will always
have a newer timestamp.
We will update bash-4.4 in a separate PR (but that one has a bigger rebuild
impact so will have to target staging)
