Comment (by essandess):

 Replying to [comment:7 essandess]:
 > * Idiosyncratically, {{{cabal}}}'s configuration specification for the C
 compiler is {{{--with-gcc}}}, and if you want {{{clang}}}, the
 documentation says to use {{{--with-gcc=clang}}}. See:
 >   * https://cabal.readthedocs.io/en/3.14/config.html#program-options
 >   * {{{cabal configure --help | grep -- --with}}}
 >   * https://github.com/haskell/cabal/issues/7899
 > * Therefore, to the best of my knowledge, I believe {{{cabal}}} should
 be configured with {{{with-gcc: ${configure.cc}}} in its top-level
 {{{config}}} file created in PG {{{haskell_cabal}}}, rather than the
 current setting {{{gcc-location: ${configure.cc}}}}, which as noted here
 wouldn't do anything.

 Followup on these comments:
 * {{{--with-gcc}}} is a {{{cabal configure}}} directive, not a valid
 {{{config}}} specification
 * Apparently the correct way to accomplish that is the way that's already
 done with {{{gcc-location}}} in {{{config}}} created by PG
 {{{haskell_cabal}}}
 * However, this {{{cabal}}} {{{config}}} setting may or may not do
 anything: https://github.com/haskell/cabal/issues/8476, and I'd say
 probably doesn't do anything by the evidence of this very issue
 * I've added @pmetzger's {{{config}}} options to PG {{{haskell_cabal}}} in
