I'm trying to build the native compiler to a arm a9 using this tutorial, https://wiki.linaro.org/WorkingGroups/ToolChain/Using/GCCNative.

It's odd that you have to set --host as ARM, since your host is x86_64.
Also, GCC might be different, but arm-unknown-eabi is a bare metal toolchain, not a linux one, maybe that's another source of problems. Try arm-linux-gnueabi for soft-float and arm-linux-gnueabihf for hard-float.
IIUC, what you are trying to do is called "Canadian Cross" build, which involves to use a cross-compiler:
- you'll use an x86_64 compiler to build a cross-compiler, running on
x86_64 and producing code for ARM.
- then you'll use this cross-compiler to cross-build the native-ARM compiler.
I believe there is some documentation in GCC about Canadian Cross builds, and I think cbuild2 supports such builds too.

Let's me explain, I want to compile that will be hosted and working in a ARM A9 Linux producing ARM binary (cross-native), but I need to create this compiler in my machine ubuntu x86_x64. Canadian cross, I think is when the three are different archs I 'm compiling now this ../configure --target=arm-none-linux-gnueabi --build=x86_64-linux-gnu --host=arm-none-linux-gnueabi, Thank you.
