Support for Cygnus-style trees has been removed

Hello!

I'm actually able to build newlib with most recent automake on Arch Linux - 
maybe that's just a issue of the configure flags that you are using? For the 
toolchain that I build I use almost the same flags as ARM uses for their bare-
metal toolchain.

newlib-cygwin/configure  \
    --target=arm-none-eabi \
    --prefix=$INSTALLDIR_NATIVE \
    --infodir=$INSTALLDIR_NATIVE_DOC/info \
    --mandir=$INSTALLDIR_NATIVE_DOC/man \
    --htmldir=$INSTALLDIR_NATIVE_DOC/html \
    --pdfdir=$INSTALLDIR_NATIVE_DOC/pdf \
    --enable-newlib-io-c99-formats \
    --enable-newlib-io-long-long \
    --disable-newlib-supplied-syscalls \
    --enable-newlib-reent-small \
    --disable-newlib-atexit-dynamic-alloc \
    --disable-newlib-fvwrite-in-streamio \
    --disable-newlib-fseek-optimization \
    --disable-newlib-wide-orient \
    --disable-newlib-unbuf-stream-opt \
    --enable-newlib-global-atexit \
    --disable-nls

With these options it works fine...
