OK, could you try this, and share the full output?
Attached is the output of “make -j4” in a build at stage1, where I have just run "rm -rf x86_64-apple-darwin17.0.0/**/libstdc++-v3”, with the patch applied.

There are two commands that create the include/ext/new_allocator.h
symlink:

Presumably for the i386 and x86_64 multilibs (does it make any
difference if you do --disable-multlib? It would be easier to debug the
output if each command was only done once).
There is no "echo 1 > stamp-ext" line, but that's because the recipe
uses @$(STAMP) stamp-ext and I didn't tell you to remove the @. In any
case, we can see the symlink being created, without any errors
printed, and yet it's not there when needed. How can the "ln" command
fail?
The last change I asked you to test should have ensured that the
stamp-ext target completed before the PCH generation, but you said
that didn't help. Is something removing those symlinks after they're
created? The .PRECIOUS: target should prevent that.
I can't really do much more by email, somebody with access to one of
these failing systems needs to debug this. The problem has nothing to
do with C++ so I don't see why it needs to be solved by libstdc++
people -- just modify the makefile and inspect the results.
