Did your Makefile actually get regenerated?

The idea is that gcc/tm.texi is no longer compared against
$(srcdir))/doc/tm.texi,
but against gcc/tmp3-tm.texi, which should have the same line endings as
gcc/tm.texi .

This temporary file is not deleted in the miscompare case, so you should be
able to inspect it, too.
