Cannot cross compile to `freebsd`, `windows` works fine

[dy-tea]

Describe the bug

I have a project that is written in V and only depends on standard V modules. I am on linux and cross-compilation to windows works fine but I get a linker error when trying the same with freebsd.

Reproduction Steps

Create the following file main.v

fn main() {
	println('Hello World!')
}

Linux on Linux:

# v -os linux main.v
# ./main
Hello World!

Windows on Linux:

# v -os windows main.v
Cross compiling for Windows...
/home/dylan/Repos/rr-dl/main.exe has been successfully cross compiled for windows.
# WINEDEBUG=-all wine main.exe

Hello World!

FreeBSD on Linux:

#  v -os freebsd main.v

See output below in Current Behavior section.

Expected Behavior

Should compile a FreeBSD executable.

Current Behavior

Cross compilation for FreeBSD failed (second step, lld).
