Gladly:

I am bootstrapping with an earlier build of GCC 7.3.0 (itself compiled via a
non-bootstrapped build, due to this issue).
cmp(1) has no version option; it is simply /usr/bin/cmp:
$ cmp
usage: cmp [-l] [-s] file1 file2 [skip1] [skip2]
$ grep 'do-compare.*=' Makefile
do-compare = cmp $$f1 $$f2 16 16
do-compare3 = $(do-compare)

Is it feasible to re-run the bootstrap with something like
CFLAGS(_FOR_(BUILD|TARGET)) = "-save-temps" ? Recreating the compiler
invocations manually will be quite tricky.
