Fix FreeBSD job

[Bodigrim]

@blackgnezdo @arrowd could you possibly help me out with this? The FreeBSD CI job used to succeed with GHC 8.10 and FreeBSD 13.0, e. g., https://cirrus-ci.com/task/4639347260522496. However, upgrading to GHC 9.2 and FreeBSD 13.1 suddenly started to fail (e. g., https://cirrus-ci.com/task/6067564724355072) with

CC @vdukhovni as another FreeBSD user, if I recall correctly.

[arrowd]

FreeBSD 13.1 ships Clang 13 which has a bug when the --target flag is passed with unexpected value.

As a workaround you can add llvm14 to the pkg install line and point cabal to clang++14 executable as a C++ compiler.

I am running into a problem with GHC 9.2 and FreeBSD 12.3-p6:

As a workaround you can add llvm14 to the pkg install line and point cabal to clang++14 executable as a C++ compiler.

Is that in the text.cabal file, or a global cabal setting (which)?

[Bodigrim]

Thanks @arrowd, cabal test --ghc-options='-pgmc clang++14' works, at least for GHC 9.2.

@Lysxia this is ready for review.

[vdukhovni]

FWIW, when I use GHC 9.4.1 instead of 9.2, the build works.

[blackgnezdo]

cabal v2-test passes on OpenBSD at both 5558730 and a7496a7 using ghc 9.2.4.

[Lysxia]

Thanks for the help!

[Bodigrim]

Thanks all for investigation!
