This reverts commit 0a944b345e, reversing
changes made to 61733ed6cc.
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.
(cherry picked from commit ec8d41f08c)
It really doesn't make sense to pass stdenv.system to the builder and
check the value during build process. Also, we're now using
$NIX_CC/nix-support/dynamic-linker instead of pattern matching on
ld-linux*.so.?.
This is part of an attempt to fix nixpkgs tarball evaluation.
