sternenseemann ccc08ba453 haskell.compiler.{ghc98*,ghcHEAD}: bootstrap using source built 9.6
Unfortunately, we are running into trouble linking dependencies of
hadrian against the libraries of the clock package with 9.6.3 and
9.6.4 _bindists_. My current suspiscion is that this is caused by
some kind of discrepancy between the toolchain used by GHC upstream
and us that persists from the configure step used when building the
bindist. The problem seems to be somewhat localized to hsc2hs (hence
clock is an issue), with GHC 9.6.4 bindists even passing a flag to
ld that is not supported by our version of cctools.

The problem is not fully diagnosed, so take the speculation above
with a grain of salt.

As a workaround, we can use the source built GHC 9.6 which is, of
course, configured with our toolchain in the environment.
