cross-compile to blackfin fails

Hi,

I got around to building my blackfin toolchain.
I have binutils and gcc built (bfin-linux-uclibc-XXX variety),
now trying to build uclibc:

...
  CC libc/inet/rpc/rpc_thread.o
  CC libc/stdlib/atexit.o
  AS lib/crt1.o
  AS lib/crti.o
  AS lib/crtn.o
  CC lib/crtreloc.o
libc/sysdeps/linux/bfin/crtreloc.c:91: warning: 'visibility' attribute ignored on non-class types
  STRIP -x -R .note -R .comment lib/libc.a
bfin-linux-uclibc-strip: 'libc/sysdeps/linux/bfin/mmap.o': No such file
  AR cr lib/libc.a
bfin-linux-uclibc-ar: libc/sysdeps/linux/bfin/mmap.o: No such file or directory
make: *** [lib/libc.a] Error 1

What puzzles me is that libc/sysdeps/linux/bfin/Makefile.arch
mentions mmap.c:

CSRC := brk.c bsdsetjmp.c clone.c syscall.c mmap.c \
        sram-alloc.c sram-free.c dma-memcpy.c

but actual file doesn't exist in libc/sysdeps/linux/bfin,
and make indeed does not build it:

...
  AR cr lib/librt.a
  CC libc/sysdeps/linux/bfin/brk.o
  CC libc/sysdeps/linux/bfin/bsdsetjmp.o
  CC libc/sysdeps/linux/bfin/clone.o
  CC libc/sysdeps/linux/bfin/syscall.o
  CC libc/sysdeps/linux/bfin/sram-alloc.o
  CC libc/sysdeps/linux/bfin/sram-free.o
  CC libc/sysdeps/linux/bfin/dma-memcpy.o
  AS libc/sysdeps/linux/bfin/__longjmp.o
  AS libc/sysdeps/linux/bfin/setjmp.o
  AS libc/sysdeps/linux/bfin/bsd-_setjmp.o
  AS libc/sysdeps/linux/bfin/vfork.o
  CC libc/sysdeps/linux/common/access.o
  CC libc/sysdeps/linux/common/acct.o
...

What I'm doing wrong?
