Apologies.  I'm using the config flags to build GCC with mpc/mpfr/gmp.
I am not building binutils.
I am using the installed GCC's sysroot in the --sysroot option.

The config flags for the current run (which just failed) are:

 ../gcc-4.7.0/configure --prefix=/usr/gcc --host=arm-linux-androideabi
--build=arm-linux-androideabi --target=arm-linux-androideabi
--enable-ppl=no --enable-ld=no --enable-libquadmath=no
--enable-libada=no --enable-cloog=no --disable-bootstrap
--enable-multilib=no --enable-multiarch=no --enable-nls=no
--disable-dependency-tracking --enable-languages=c,c++
--with-sysroot=/usr/local/sysroot --with-ld=/usr/local/bin/ld
--with-build-time-tools=/usr/local/bin --enable-languages=c,c++
"LIBS=-lc -ldl -lm -lgcc -lstdc++" "CFLAGS=-marm -mandroid -mbionic"
"CXXFLAGS=-mandroid -mbionic" "CPPFLAGS=-mandroid -mbionic"
LDFLAGS=-Wl,--dynamic-linker=/system/bin/linker "LIB_PATHS=/lib
/usr/lib" "SHELL=/system/bin/sh" "CONFIG_SHELL=/system/bin/sh"

Do I need to download the source for binutils and build it as well?
