I tried, but it does not work, either.

Below is from the config.log of libgloss, which was generated when
building newlib:

/home/jie/Sources/newlib-1.15.0/libgloss/configure
--cache-file=./config.cache --build=i686-pc-linux-gnu --host=bfin-elf
--target=bfin-elf --with-newlib --with-cross-host=i686-pc-linux-gnu
--prefix=/home/jie/installs/bfin-41-217/ --enable-interwork
--enable-multilib --program-transform-name=s,^,bfin-elf-,;
--with-target-subdir=bfin-elf
--srcdir=/home/jie/Sources/newlib-1.15.0/libgloss

I created a new build directory and run this command. I got:

Then when make, it still tried to use native gcc.
