2493454e13 cc-wrapper: Use set -u throughout
Now is an opportune time to do this, as the infixSalt conversion in
`add-flags.sh` ensures that all the relevant `NIX_*` vars will be
defined even if empty.

9f1e009975 cc-wrapper: Unconditionally use @infixSalt@ accross the board
This is basically a sed job, in preparation of the next commit. The
rules are more or less:

  - s"NIX_(.._WRAPPER_)?([a-zA-Z0-9@]*)"NIX_\1@infixSalt@_\2"g

  - except for non-cc-wrapper-specific vars like `NIX_DEBUG`

6463fd3d7e cc-wrapper: Pass shellcheck and other cleanups
In many cases, this involved taking @orivej's and @edolstra's recent
ld-wrapper improvements, and applying then elsewhere.

ab15a62c68 Merge branch 'master' into closure-size
Beware that stdenv doesn't build. It seems something more will be needed
than just resolution of merge conflicts.

f89a136fd5 cc-wrapper: fixup branch interactions
c0599fdd61 and changes on closure-size didn't go well together.

d96893647d cc-wrapper: fix on darwin
The ld-wrapper.sh script calls `readlink` in some circumstances. We need
to ensure that this is the `readlink` from the `coreutils` package so
that flag support is as expected.

This is accomplished by explicitly setting PATH at the top of each shell
script.

Without doing this, the following happens with a trivial `main.c`:

```
nix-env -f "<nixpkgs>" -iA pkgs.clang
$ clang main.c -L /nix/../nix/store/2ankvagznq062x1gifpxwkk7fp3xwy63-xnu-2422.115.4/Library -o a.out
readlink: illegal option -- f
usage: readlink [-n] [file ...]
```

The key element is the `..` in the path supplied to the linker via a
`-L` flag. With this patch, the above invocation works correctly on
darwin, whose native `/usr/bin/readlink` does not support the `-f` flag.

The explicit path also ensures that the `grep` called by `cc-wrapper.sh`
is the one from Nix.

Fixes #6447

48f63c2f2e rename gcc-wrapper to cc-wrapper.
also makes cc-wrapper compatible with clang in the darwin fork.
