Strange, I have given the configure options I always use - never 
tried script so cannot verify.

** gcc build **
./configure --target=arm-elf --prefix=/sarm-elf --enable-interwork --
enable-multilib --disable-nls --disable-win32-registry --disable-
shared --enable-languages="c,c++" --with-newlib --with-headers=/sarm-
build/newlib-1.13.0/newlib/libc/include
make all-gcc install-gcc 2>&1 | tee make-gcc.log

** newlib **
./configure --target=arm-elf --prefix=/sarm-elf --enable-interwork --
enable-multilib --disable-nls --disable-win32-registry --disable-
shared --enable-target-optspace=yes
make all install 2>&1 | tee make.log

** gcc full build **
make all install 2>&1 | tee make.log

Hope it helps.
