Looks like you're having problems with fileno() being passed a void pointer. Try compiling with:

  make FILENO_IS_A_MACRO=Yes

That is generally set automatically on FreeBSD via config.mak.uname; perhaps you missed it when moving things around there.

I've never tried cross-compiling Git, but I'd guess that your best bet is to override the uname_* variables, like:

  make uname_S=FreeBSD uname_R=13.2

(there are others, but those are the main ones we use to set defaults for various Makefile knobs). Of course you can tweak all the Makefile knobs yourself, but that may be tedious.
