includes a version number in the path.

The musl support for binary GHC 8.6.5 relied on ABI compat between musl
and glibc which is no longer the case: https://github.com/NixOS/nixpkgs/issues/129247
Since there is no upstream musl (alpine) bindist for GHC 8.6.5, we can
only accept that binary 8.6.5 is not possible with musl.
There are builds which rely on having the numeric version of gcc (eg "10.2.1")
declared in an environment variable.
Running 'arm-none-eabi-gcc --version' returns:
"arm-none-eabi-gcc (GNU Arm Embedded Toolchain 10-2020-q4-major) 10.2.1 20201103 (release)"
However, the attribute arm-none-eabi-gcc.version is "10-2020-q4-major",
from which there is no way to derive "10.2.1".
Contrast this with the attribute gcc.version which (at this time) gives "10.3.0".
By adding a numVersion attribute, consumers of this package can
correctly determine what GCC version is being executed.

Adds new package options:
* enableDocs
* enableHaddockProgram
to control whether to build Sphinx docs, and GHC haddocks and the
haddock program.
Unfortunately currently the building of the `haddock `program
and generating GHC docs are mixed into one option, see:
https://gitlab.haskell.org/ghc/ghc/-/issues/20077
Making Sphinx docs disableable, and disabling them by default
for Musl and cross builds, makes it much easier to provide these
builds without having to support Sphinx's enormous dependency
tree for those ways of building.
This addresses the fact that `ghc865Binary` segfaults on musl
(see #118731) because of the glibc+musl mix used in there.
With the previous commits, `ghc8102Binary` was changed to use
the musl-based bindist from GHC HQ instead, which works.
With this change, all nix Haskell compilers builds on musl:
NIX_PATH=nixpkgs=. nix-build --no-link --expr 'with import <nixpkgs> {}; { inherit (pkgsMusl.haskell.compiler) ghc884 ghc8104 ghc901 ghcHEAD; }'
This commit replaces the musl + glibc hackery in the GHC bindist
compiler by using the new musl based bindist that GHC HQ provides
(built on Alpine).
We could alternatively also use a nix-built musl boostrap compiler,
but it seems nicer to use the GHC HQ one for now.
This fixes the compiler built by
`pkgsMusl.haskell.compiler.ghc8102Binary` segfaulting (#118731)
since the commit
5e2311d2f - musl: 1.2.1 -> 1.2.2
concretely, musl commit
01c7920f - remove redundant pthread struct members repeated for layout purposes
which I suspect breaks some glibc/musl ABI compatibility that may have
existed accidentally until then.
The added
lib.optional stdenv.targetPlatform.isMusl "pie";
also fixes that the packaged bindist compiler cannot create a binary
in its `installCheck` phase (and overall); see detail explanation
in #129247.
With this check, we no longer don't notice when the upstream bindist
changes its dependencies (e.g. because a newer Debian version is used
that uses a new `ncurses` version).
