Log message:
lang/ghc94: Fix broken "make bootstrap"

Bootstrapping the compiler without "cabal-install" is something GHC devs
rarely do, and it keeps bitrotting. This time I could make it work again,
but at some point we might end up having to distribute binaries of
cabal-install for each platform.

Log message:
lang/ghc94: Fix build of hadrian/bootstrap with cabal-install-parsers >= 0.6

Log message:
*: recursive bump for Python 3.11 as new default

Log message:
Mass-change BUILD_DEPENDS to TOOL_DEPENDS outside mk/.

Almost all uses, if not all of them, are wrong, according to the
semantics of BUILD_DEPENDS (packages built for target available for
use _by_ tools at build-time) and TOOL_DEPEPNDS (packages built for
host available for use _as_ tools at build-time).

No change to BUILD_DEPENDS as used correctly inside buildlink3.

As proposed on tech-pkg:
https://mail-index.netbsd.org/tech-pkg/2023/06/03/msg027632.html

Log message:
ghc94: Switch PYTHON_FOR_BUILD_ONLY to "tool".

Setting it to "yes" performs a full buildlink3 inclusion of the necessary
python version.  This brings in gettext-lib, which on some platforms will add
an explicit -lintl to linker args, but gettext-lib is not marked as a full
dependency so this ends in runtime failures with missing libintl.

Switching to "tool" uses a plain DEPENDS instead so no problems.
