Comment (by boklm):

 I have been building using `-Wl,-t` two times on one machine, and one time
 on an other one. The builds from the same machine were identical, but
 different on the second machine.

 Comparing the logs from the non maching builds, the main difference was
 the order of `.o` files included inside `libstdc++.a`. It seems that with
 previous versions of binutils, the order of objects inside a `.a` file did
 not affect the output, but it is not the case anymore with more recent
 versions of binutils.

 The reason why `libstdc++.a` is including objects in random order is that
 gcc is using an old version of libtool:
 https://gcc.gnu.org/ml/gcc-patches/2018-06/msg01115.html

 With the libtool patch sorting the output of `find`, I am now able to get
 matching builds on different machines.

 I am now testing a patch to update binutils to 2.31.1.
