I agree.

I can try a respin of my compiler-rt/libFuzzer patches to add a built-in
fork-server to libFuzzer, so we can avoid the linker-script madness
altogether. Don't know how soon I can get to this, but I do think it is
worth another try.

TIL about these differences between ld.bfd and ld.gold.
So the idea is to use something like:
"ld --verbose | grep -n ".*:" | grep -A1 "\s.data\s" | tail -n1"
and insert the existing linker-script before that line?
Thanks
