Since at least d7bddc27b2, we've had a
situation where one should depend on:
- `stdenv.cc.bintools`: for executables at build time
- `libbfd` or `libiberty`: for those libraries
- `targetPackages.cc.bintools`: for exectuables at *run* time
- `binutils`: only for specifically GNU Binutils's executables,
regardless of the host platform, at run time.
and that commit cleaned up this usage to reflect that. This PR flips the
switch so that:
- `binutils` is indeed unconditionally GNU Binutils
- `binutils-raw`, which previously served that role, is gone.
so that the correct usage will be enforced going forward and everything
is simple.
N.B. In a few cases `binutils-unwrapped` (which before and now was
unconditionally actual GNU binutils), rather than `binutils` was used to
replace old `binutils-raw` as it is friendly towards some cross
compilation usage by avoiding a reference to the next bootstrapping
change.
On most distros, these are just built and distributed as part of
binutils. We don't use binutils across the board, however, but rather
switch between binutils and a cctools-binutils mashup, and change the
outputs on binutils too. This creates a combinatorial conditional soup
which is hard to maintain.
My hope is to lower the the state space. While my patch isn't the most
maintainable, they make downstream packages become more maintainable to
compensate. The additional derivations themselves are completely
platform-agnostic, always they always supports all possible target
platforms, and always yield "out" and "dev" outputs. That, in turn,
allows downstream packages to not worry about a dependency
shape-shifting under them.
In fact, the actual binutils package can avoid needing multiple outputs
now that these serve the requisite libraries, so that also can become
simpler on all platforms, too, removing the original wart this PR
circumnavigates for now. Actually changing the binutils package to
leverage is a mass rebuild, however, so I'll leave that for a separate
PR.
I do hope to upstream something like my patch too, but until then I'll
make myself maintainer of these derivations
