Yes, I agree, my patches are quick and dirty. I was far too much of a
coward to even think about a complete fix. Though some of the things
in the patches, especially Brian Zhou's, should be completely
non-controversial, e.g.

-DED_LD=ld
+if test "x$LD" = x; then
+ DED_LD=ld
+else
+ DED_LD=$LD
+fi

but still they get ignored. I'm guessing there aren't any paying
customers that need cross compilation.

Yes, exactly. And it's going to be unpleasant, unglamorous and thankless
work. I bet it's at the top of someone's list ;-)
