[Clfs-support] Binutils for ARM devices

[Michele Bucca]

 I already have a musl cross-compiler. Now I want to use that
cross compiler to make a musl toolchain that runs on the ARM target.
However when I try to build binutils I get this nasty error about libiberty
(See Below) Can I avoid building libiberty alltoghether?

../binutils-2.27/configure --host=arm-linux-musleabi
--target=arm-linux-musleabi --build=x86_64-linux-gnu --disable-nls
--disable-multilib --prefix=/home/michele/toolchain-arm

The error
