Hi! I have recently shifted from EndeavourOS to FreeBSD, and I am having an interesting problem with building packages.

If I am to cargo install a crate, it builds well enough, and I can run the resultant executable just fine. However, if I am to cargo build a crate, I get a linker error of the following flavour

 = note: ld: error: undefined symbol: main
         >>> referenced by crt1_s.S:64 (/usr/src/lib/csu/amd64/crt1_s.S:64)
          >>>               /usr/lib/Scrt1.o:(_start)

This was from an empty crate produced with cargo new, with no dependencies whatsoever. I could reproduce it from both the rustc installed from the FreeBSD ports tree, as well as that installed by rustup.

How can I circumvent this?
