hadrian: Don't use mk/config.mk.in

Ultimately we want to drop mk/config.mk so here I extract the bits
needed by the Hadrian bindist installation logic into a Hadrian-specific
file. While doing this I fixed binary distribution installation, #21901.

hadrian: Extend xattr Darwin hack to cover /lib

As noted in #21506, it is now necessary to remove extended attributes
from `/lib` as well as `/bin` to avoid SIP issues on Darwin.

Fixes #21506.

rts: remove redundant stg_traceCcszh

This out-of-line primop has no Haskell wrapper and hasn't been used
anywhere in the tree. Furthermore, the code gets in the way of !7632, so
it should be garbage collected.

Document a divergence from the report in parsing function lhss.

GHC is happy to parse `(f) x y = x + y` when it should be a parse error
based on the Haskell report. Seems harmless enough so we won't fix it
but it's documented now.

Fixes #19788

gitlab-ci: Fix ARMv7 build

It appears that the CI refactoring carried out in
5ff690b8474c74e9c968ef31e568c1ad0fe719a1 failed to carry over some
critical configuration: setting the build/host/target platforms and
forcing use of a non-broken linker.
