GRUB code expects O32 or N32. N32 is less tested than O32, so we prefer to compile with O32. Some systems (e.g. GNU Guix) default to using newer n64 or n32 ABI. Try to find suitable options to force o32. For GCC this is simply -mabi=32. While clang supports this option as well, o32 ABI is valid for MIPS target and n32/64 ABI are valid for MIPS64 target only, so use "-target mips/mipsel -mabi=32".

This is GRUB 2, the second version of the GRand Unified Bootloader. GRUB 2 is rewritten from scratch to make GNU GRUB cleaner, safer, more robust, more powerful, and more portable. See the file NEWS for a description of recent changes to GRUB 2. See the file INSTALL for instructions on how to build and install the GRUB 2 data and program files. Please visit the official web page of GRUB 2, for more information. The URL is <http://www.gnu.org/software/grub/grub.html>. More extensive documentation is available in the Info manual, accessible using 'info grub' after building and installing GRUB 2. Please look at the GRUB Wiki <http://grub.enbug.org> for testing procedures. There are a number of important user-visible differences from the first version of GRUB, now known as GRUB Legacy. For a summary, please see: info grub Introduction 'Changes from GRUB Legacy'
