Description of changes

FreeBSD doesn't use LLVM's cxxabi implementation, for backwards compatibility reasons. Software expects the libcxxrt API when building on FreeBSD. This fixes the build of pkgsCross.x86_64-freebsd.boost.

Things done
  • Built on platform(s)
    • x86_64-linux
    • aarch64-linux
    • x86_64-darwin
    • aarch64-darwin
  • For non-Linux: Is sandbox = true set in nix.conf? (See Nix manual)
  • Tested, as applicable:
  • Tested compilation of all packages that depend on this change using nix-shell -p nixpkgs-review --run "nixpkgs-review rev HEAD". Note: all changes have to be committed, also see nixpkgs-review usage
  • Tested basic functionality of all binary files (usually in ./result/bin/)
  • 23.05 Release Notes (or backporting 22.11 Release notes)
    • (Package updates) Added a release notes entry if the change is major or breaking
    • (Module updates) Added a release notes entry if the change is significant
    • (Module addition) Added a release notes entry if adding a new NixOS module
    • (Release notes changes) Ran nixos/doc/manual/md-to-db.sh to update generated release notes
  • Fits CONTRIBUTING.md.

Huh, I guess this doesn't really need to target staging.

llvmPackages: don't exclude FreeBSD from -lunwind
0bab802 
The exception for FreeBSD was added in 0afe9d1 ("freebsd packages:
Init at 13.1"), but it seems to have been erroneous, as e.g. ncurses
fails to build:

	x86_64-unknown-freebsd13-clang++  -o demo ../obj_s/demo.o -L../lib -lncurses++w -L../lib -lformw -lmenuw -lpanelw -lncursesw   -lutil     -DHAVE_CONFIG_H -DBUILDING_NCURSES_CXX -I../c++ -I. -I../include  -DNDEBUG -O2  -fPIC -DPIC
	x86_64-unknown-freebsd13-ld: error: undefined symbol: _Unwind_Resume
	>>> referenced by demo.cc
	>>>               ../obj_s/demo.o:(TestApplication::run())
	>>> referenced by demo.cc
	>>>               ../obj_s/demo.o:(_GLOBAL__sub_I_demo.cc)
	>>> referenced by demo.cc
	>>>               ../obj_s/demo.o:(NCursesUserItem<UserData>::NCursesUserItem(char const*, char const*, UserData const*))
	>>> referenced 46 more times
	clang-12: error: linker command failed with exit code 1 (use -v to see invocation)

This is fixed by undoing the change, adding -lunwind on FreeBSD.

I've split the -lunwind change into its own commit, since it turns out it's needed independently of the change to libcxxrt. But I don't think there's any point in splitting it into a separate PR.

Updated to be less stringy based on a suggestion from @Ericson2314 on Matrix. We now pass cxxabi around as a package, and look at its pname when necessary to tell them apart, rather than passing a string around and trying to map it back to a packag.
