Here is the updated version of the patch.
Which also included some (clearly identifiable) hunks that did not
belong in the patch. They are not triggered without toplevel bootstrap,
but here is the patch without them.
I have been using this patch daily for weeks (even though I don't build
Ada, so the original bug does not show up for me and most other people
using unified trees). I would be okay also with approval for 4.2 and a
later backport, since the branch is going to happen RSN. Though, let me
recall that Joel Sherrill has also tested this patch quite heavily.

* configure.in (CONFIGURED_BISON, CONFIGURED_YACC, CONFIGURED_M4,
CONFIGURED_FLEX, CONFIGURED_LEX, CONFIGURED_MAKEINFO): Remove
"CONFIGURED_" from the AC_CHECK_PROGS invocation. Move below.
Find in-tree tools if available.
(EXPECT, RUNTEST, LIPO, STRIP): Find them and substitute them.
(CONFIGURED_*_FOR_TARGET): Don't set nor substitute.
(*_FOR_TARGET): Set them with GCC_TARGET_TOOL.
(COMPILER_*_FOR_TARGET): New.
* Makefile.tpl (HOST_EXPORTS): Add *_FOR_TARGET symbols that gcc needs.
(EXTRA_HOST_FLAGS): Pass LIPO and STRIP.
(BASE_TARGET_EXPORTS, EXTRA_TARGET_FLAGS): Use COMPILER_*_FOR_TARGET
symbols.
(CONFIGURED_*, USUAL_*): Remove.
(BISON, YACC, FLEX, LEX, M4, MAKEINFO, EXPECT, RUNTEST, LIPO,
STRIP): Use autoconf substitutions.
(COMPILER_AS_FOR_TARGET, COMPILER_LD_FOR_TARGET,
COMPILER_NM_FOR_TARGET): New.
(all): Make all-host and all-target in parallel. When bootstrapping,
invoke stage3-bubble.
(stage[+id+]-bubble): Likewise, and invoke the comparison at the end.
([+bootstrap-target+]): Inline most of the `all' target.
