Key test case: nixpkgs#pkgsStatic.pkgsLLVM.ncurses Prior to this patch, this fails with errors such as: ``` error: undefined symbol: __cxa_throw ``` I think this is a reasonable solution because in #292043, libcxxabi was 'merged into libcxx', however, the commit message suggests that only dynamic linking was accounted for, because it says: ``` * linux/freebsd `libc++.so` is a linker script `LINK(libc++.so.1, -lc++abi)` making `-lc++` sufficient. ``` Whereas, I found that if I tried linking a "hello world" C++ program with a static hostPlatform, it failed unless -lc++abi was passed.
