Comment:
> I've now added a patch for configure.ac and Makefile.am (as well as re-genned configure and Makefile.in) so that the gcc build system is doing the heavy lifting. These changes mostly came from looking at a diff between gcc/libbacktrace and ianlancetaylor/libbacktrace.

The upstream build still puts it inside `.libs`, this doesn't change that. A 1k GCC patch is not the solution here, please revert to the version with the manual install commands.
