This is going to be a rolling state of portage which may be why it broke.

This fails to build glibc, but doesn't exactly give much info:

   * Log: /var/log/portage/cross-mipsr5900el-unknown-linux-gnu-binutils.log
   * Emerging cross-binutils ...                                            [ ok ]

   * /var/tmp/portage/cross-mipsr5900el-unknown-linux-gnu/glibc*/temp/glibc-config.logs.tar.xz
  The command '/bin/sh -c crossdev -s3 -t mipsr5900el-unknown-linux-gnu --binutils ">=2.30" --gcc ">=7.2.0"' returned a non-zero code: 1

But running in a container I did get:
