GCC 4.9.2 Build Fails at cc1

[Cyd Haselton]

Hello,
After downloading and unpacking  the source, creating the build
directory and running ./contrib/download_prerequisites, I run
configure with the following options:

../gcc-4.9.2/configure --prefix=/usr/gcc-4.9
--build=arm-linux-androideabi --host=arm-linux-androideabi
--target=arm-linux-androideabi --disable-ld
--with-as=/usr/gcc-4.9/bin/as --with-ld=/usr/gcc-4.9/bin/ld

LDFLAGS=-Wl,--dynamic-linker=/system/bin/linker

And during make, this happens:

Previously I thought this occurred because I was using the wrong
versions of mpfr/gmp and mpc...until I started over and ran the
download_prerequisites.

Any idea what could be wrong?
