The target system.

What chicken version were you using? Could you supply a build log?

The "-host" option (which here is supplied to csc) tells the compiler
to not use the target C compiler and linker, but the host one. It is
intended to tell a specially built "cross" chicken to differentiate
between the C compilers for the host and the target system
(or build and host, which would be the autotools naming
convention). But the cross-linux-mingw platform just builds
a system for the target machine and the resulting binaries
are to be used there, so it is not what is called a "cross" chicken.
