Hi, Sam & Ralf
Perhaps we also need to fix the following stuff:
mips64el-unknown-linux-gnu-objcopy -O elf32-tradlittlemips
--remove-section=.reginfo vmlinux vmlinux.32
The related Makefile is arch/mips/Makefile:

> 723 # Other need ECOFF, so we build a 32-bit ELF binary for them which we then
> 724 # convert to ECOFF using elf2ecoff.
