It simply fails to build on my amd64 box, even with MAKEOPTS="-j1":

As I watched your emerge_info, may be the issue related with using the ~arch as you used GCC 10.x to build.

I can't reproduce this issue here since I'm using the 9.3.0 version.

Please, try with that version and tell me what's going on.

Looks like the same error with gcc 9.3.0.
