Reverts #162607 / 1748887ff2.
Reason for revert: This change caused llvm-config{,-native} to be unable
to find static archives bundled with LLVM, as has been [reported]. Ever
since #152944 using moveToOutput in LLVM is _evil_ because llvm-config
obtains it knowledge about the installation locations from the CMake
configure step.
Consequently a change like #162607 will need to be implemented by making
LLVM itself install the static archives to the correct location or by
adding yet another patch which updates llvm-config's knowledge of the
location. The latter is not desireable in my opinion, though, since it
is just asking for this sort of trouble: Before #152944 we had an
outputs.patch that did this sort of things which broke spectacularly in
edge cases.
Fixes#148117.

Without the change build fails on darwin as:
duplicate symbol '_static_code_space_free_pointer' in:
alloc.o
traceroot.o
duplicate symbol '_static_code_space_free_pointer' in:
alloc.o
gencgc.o
Without the change -fno-common toolchain like llvm-11 fails as:
ld: libcamlrun.a(minor_gc.o):/build/ocaml/byterun/caml/major_gc.h:67: multiple definition of
`caml_major_ring'; libcamlrun.a(stacks.o):/build/ocaml/byterun/caml/major_gc.h:67: first defined here
Since the musl / alpine bindist now uses the GMP backend, we need to
learn to tell Hadrian bindists about GMP. Hadrian bindists no longer
have the buildinfo files, instead we need to patch the package db before
installing and recache it afterwards which is not too hard, luckily.
Same goes for libiconv and base as well as libffi and rts on
darwin (those bindists are all produced using hadrian).

Note that pkgsMusl.haskell.compiler.ghc922Binary still has severe
issues: It can't produce shared libraries because the bindist ships
none (and using the GMP backend has a hard requirement for shared
objects, apparently) and ghci segfaults for unknown reasons at the
moment. However, I've successfully compiled hadrian with it so far, so
perhaps it's good enough.
If HARECACHE is unset, it hare will default to attempting to cache files
relative to $HOME, which isn't writable during a build. Set HARECACHE to
a suitable location so packages that are built with hare don't have to
manually handle this.
A few complex math tests have been failing since they were added, so
disable the failing cases for now.
