newlib error while cross compiling gcc

[Yogesh Wani <yogeshwani at gmail dot com>]

Hi

I am trying to build  the gnu gcc toolchain for arm7tdmi cpu and I
encountered the following error when doing the make for gcc. What is
the resolution for this? Please help !

the packages I am using are
binutils: binutils-2.25
newlib:  newlib-2.2.0.20150323
gcc:      gcc-4.9.2
gmp:     gmp-6.0.0
mpc:     mpc-1.0.3
mpfr:     mpfr-3.1.2

gcc is configured as follows

~/armtoolchain/src/gcc-4.9.2/configure --target=arm-none-eabi
--prefix=/home/yogesh/armtoolchain/binaries/ --enable-languages=c,c++
--with-gnu-as --with-gnu-ld --with-newlib
--with-gxx-include-dir=/home/yogesh/armtoolchain/binaries/arm-none-eabi/include
--with-cpu=arm7tdmi --with-gmp=/home/yogesh/armtoolchain/binaries
--with-mpfr=/home/yogesh/armtoolchain/binaries
--with-mpc=/home/yogesh/armtoolchain/binaries
