Hi,

Thanks for the reply and I apologize for my ignorance.

I need to create linux binaries of my tools that will run on any x86
linux distribution. So I can compile them once and copy to other linux
machines. As I understood i686-elf target should be best choice for
this.

x86_64-unknown-linux-gnu and then use it to build cross compiler.

I wasn't aware that having gmp, mpfr and mpc inside gcc source
directory doesn't have the same effect as using --with-gmp,
--with-mpfr and -with-mpc. But that's a good point, I'll try it.

I noticed that I had --without-headers option missing right after
posting so I added it and tried again. Unfortunately there's not
difference. I still get the same error:
