rts, tests: limit thread name length to 15 bytes
On Linux, `pthread_setname_np` (or rather, the kernel) only allows for
thread names up to 16 bytes, including the terminating null byte.
This commit adds a note pointing this out in `createOSThread`, and fixes
up two instances where a thread name of more than 15 characters long was
used (in the RTS, and in a test-case).
Fixes: #22366

Store bootstrap_llvm_target and use it to set LlvmTarget in bindists
This mirrors some existing logic for the bootstrap_target which
influences how TargetPlatform is set.
As described on #21970 not storing this led to `LlvmTarget` being set incorrectly
and hence the wrong `--target` flag being passed to the C compiler.
Towards #21970

Check for FP_LD_NO_FIXUP_CHAINS in installation configure script
Otherwise, when installing from a bindist the C flag isn't passed to the
C compiler.
This completes the fix for #22429

Give the RTS it's own configure script
Currently it doesn't do much anything, we are just trying to introduce
it without breaking the build. Later, we will move functionality from
the top-level configure script over to it.
We need to bump Cabal for https://github.com/haskell/cabal/pull/8649; to
facilitate and existing hack of skipping some configure checks for the
RTS we now need to skip just *part* not *all* of the "post configure"
hook, as running the configure script (which we definitely want to do)
is also implemented as part of the "post configure" hook. But doing this
requires exposing functionality that wasn't exposed before.
