wchar_t is i32 for all bsd targets

[gnzlbg]

AFAICT wchar_t is i32 for all BSD targets, but for example for FreeBSD aarch64 targets it should be u32. I'm not sure about ios aarch64 targets, but i think there it is also u32.

cc @asomers - we are not testing aarch64-freebsd on CI, so this might be worth fixing.

Testing aarch64-freebsd in CI would require usermode qemu emulation. It's possible, but it would take some effort to setup.

Oh, there's a new option now. Cirrus CI can do CI testing on arm64. Currently they only do it for Linux, but it would be easy to add FreeBSD, if there's enough interest.
