You can configure with "--enable-languages=c --target=mips-linux" only and add
-mexplicit-relocs to compile flags:
/ssd/uros/gcc-build-mips/gcc/xgcc -B /ssd/uros/gcc-build-mips/gcc -O -ftree-vrp
-fcompare-debug -S -mexplicit-relocs pr43670.c
xgcc: error: pr43670.c: -fcompare-debug failure (length)
Confirmed - my patch just exposed the problem in generic RTL code.
