--- Comment #14 from Hime Haieto <himehaieto at gmail dot com> --- It could still be worth doing a couple other "easy" tests first before going more fully into the Makefile.am - skipping a separate make step (i.e. configure then straight to make install), and if there's maybe a way to make it stop trying to build the 32-bit version (note from the original error message that it's trying to build libbacktrace for both 64/32 and seems to fail when it comes back around for 32). Of course, note also that patching line 107 of the above Makefile.am to add a -f after $(LN_S) should also "fix" the problem, but as mentioned about autotools conventions, merely seeing that target in the file at all is a major build code smell, and it should ideally be fixed properly.
