That document is out of date with regards to this.

Libgloss is relying on some variables being set in the top-level 
configuration.  As well, libgloss needs to use newlib's header files.

There are two alternatives:

1) configure as you would normally do for top-level configure

   perform: make all-target-libgloss install-target-libgloss

   This will configure newlib, but only builds libgloss

2) Manually specify things that top-level configure does for you:

../src/libgloss/configure --host=bfin-elf CC=bfin-elf-gcc AR=bfin-elf-AR 
LD=bfin-elf-ld RANLIB=bfin-elf-ranlib AS=bfin-elf-as CCAS=bfin-elf-gcc

   make CFLAGS=-I$PATH/src/newlib/libc/include
