It's a one-line file generated at build time by cc_tools/Makefile:
config.h hconfig.h tconfig.h:
echo '#include "${MACHINE_ARCH}/xm-freebsd.h"' > ${.TARGET}
which includes src/contrib/gcc/config/<arch>/xm-freebsd.h, which in
turn includes src/contrib/gcc/config/<arch>/xm-<arch>.h and
src/contrib/gcc/config/xm-freebsd.h, which defines:
#define HAVE_PUTENV
#define HAVE_STRERROR
#define DONT_DECLARE_SYS_SIGLIST
#define HOST_PTR_PRINTF "%p"

If you're continuing on your way to extracting it completely from the
tree, the PR should be ignored for now, correct?
