Dear Maintainer,

Build fails here:

Comparing stages 2 and 3
warning: gcc/cc1objplus-checksum.o differs
warning: gcc/cc1obj-checksum.o differs
warning: gcc/m2/gm2-compiler-boot/M2Version.o differs
Bootstrap comparison failure!
gcc/SYSTEM.o differs

SYSTEM.o is probably a m2 file.  Not sure why it's in gcc directory.
It seems to be excluded when its in gcc/m2/gm2-compiler-boot:

# DP: ignore gm2version.o stage diff on some archtectures (m68k, riscv64)
