The following programs get compiled.

./bash/bash.exe
./bash/bashversion.exe
./bash/builtins/mkbuiltins.exe
./bash/mksignames.exe
./bash/mksyntax.exe
./diffutils/src/cmp.exe
./diffutils/src/diff.exe
./diffutils/src/diff3.exe
./diffutils/src/sdiff.exe
./grep/src/grep.exe

So the problem is in coreutils.

Installed programs fail to run.

Also make setup-test-negotiate fails.
