I have been trying to build a GNU toolchain that targets my host machine (you could call this a cross compiler or a compiler with a prefix). I have been following these instructions, but differing from them in some of my configuration options and my code versions. I make it to step 6 fine, where I need to build glibc in full. Once there, I get the following compilation error:

I am unsure how to go about fixing this error, and I have found next-to-no information online regarding it. I thought that disabling AVX when compiling might fix this, but I would like to stay away from that if possible (I also didn't see a direct way to do this while compiling glibc).

The versions of the source I am building are below. I am able to change the glibc version, but the others need to stay the same (I am doing comparisons of GNU-specific and musl-specific toolchains).

• binutils-2.33.1
• glibc-2.32
• gcc-9.2.0
• gmp-6.1.2
• mpc-1.1.0
• mpfr-4.0.2

My system has gcc-10.2.1 and glibc-2.31.

My differing configurations are as follows:

Thank you for your help!

UPDATE

I tried dialing back my configure options to the basic ones in the article linked above, but I still get the same errors. This leads me to believe that the errors are the result of a missing step or that the steps laid out in the article are dated.
