8e557ed2c5 bintools-wrapper: Init 
Factor a bintools (i.e. binutils / cctools) wrapper out of cc-wrapper. While
only LD is wrapped, the setup hook defines environment variables on behalf of
other utilites.

Revert "Merge pull request #28557 from obsidiansystems/binutils-wrapper" 
This reverts commit 0a944b345e89ca0096974d168f49e1c6830c3fc2, reversing
changes made to 61733ed6ccde3427016720f2e0cd191d3d95152c.

I dislike these massive stdenv changes with unclear motivation,
especially when they involve gratuitous mass renames like NIX_CC ->
NIX_BINUTILS. The previous such rename (NIX_GCC -> NIX_CC) caused
months of pain, so let's not do that again.

97a48835b7 mkDerivation, cc-wrapper: Check hardening flag validity in Nix 
This becomes necessary if more wrappers besides cc-wrapper start
supporting hardening flags. Also good to make the warning into an
error.

Also ensure interface is being used right: Not as a string, not just in
bash.

822a8d0148 cc-wrapper: Remove redundant hardening 
GCC just passes `-z ...` flags to ld unaltered, and they are already
passed to LD anyways. On the other hand, `-pie` affects gcc behavior
too.

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.

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.
