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.
Same adjustment as made for libc++abi in #185766, for the same reason:
the unamended dylib links to the libc++abi in the build stdenv, which
is the wrong version.
Tested on Darwin with LLVM 14 stdenv, but the phase is added to all
versions, including 11 - so this will cause a mass rebuild.

The new LLVM commit is just before the LLVM 15 fork off.
The readme describing upgrade process so it is easier for others to do.

substituteStream(): WARNING: pattern '# define _LIBCPP_USE_AVAILABILITY_APPLE' doesn't match anything in file 'include/__config'
The new mechanism for those is a cmake option
LIBCXX_ENABLE_VENDOR_AVAILABILITY_ANNOTATIONS that is off by default:

The version will initially remain the same so that no additional changes
to the packaging are required (i.e. this commit only includes the
required changes to build from the mono repository instead of individual
tarballs).
The purpose of this package is to continuously improve the LLVM
packaging in Nixpkgs without causing a lot of rebuilds and provide more
recent LLVM builds for users. For more details see:
https://github.com/NixOS/nixpkgs/issues/114828
