--- Comment #7 from Francois-Xavier Coudert <fxcoudert at gcc dot gnu.org> ---
So, to summarise my understanding:
- the problem is not specific to darwin, I can fully reproduce on
x86_64-linux-gnu
- the problem only arises if you configure with a --program-suffix that is
equal to the version. Then $(target_noncanonical)-gcc-$(version) is equal to
$(GCC_TARGET_INSTALL_NAME) and this triggers the issue.
I am not sure if it is the cleanest way to fix things, but I think we can
safely remove the temporary file after "mv", in all cases, like this:
diff --git a/gcc/Makefile.in b/gcc/Makefile.in
index 97e5450ecb5..602c382e86e 100644
--- a/gcc/Makefile.in
+++ b/gcc/Makefile.in

I can confirm this fixes the issue.
